Ctrl+Shift+Return: Keys to Your Computer
By Mike PopeOctober 15, 2012
Your computer's keyboard has around 110 keys by which you can make your wishes known to the machine. Most of these have obvious labels: if you press the A key, the letter A appears on the screen. Some are less obvious, though — the Shift key and the mysterious Ctrl key — and in this article I'll explore why they're named what they're named.
Long before computers, many practical issues about using a machine to write had already been worked out for the typewriter. If you've never used a typewriter, you might be interested in this video that shows one in action.
Consider the code block below. What is the value of amount when this method is called twice, the first time using cookieJar(7) and then using cookieJar(22)?
public static int cookieJar(int addCookies) {
int amount = 0;
amount += addCookies;
return amount;
}
A. 7
B. 15
C. 22
D. 29
E. An error occurs
Answer:
C. 22
Explanation:
Given that the argument is being passed by value, there is no memory to consider. So cookieJar(7) returns 7 and cookieJar(22) returns 22.
If the argument parameter was passed by reference or pointer, then perhaps the value from cookieJar(7) would be considered with cookieJar(22).
Note, this code block really isn't doing anything other than returning the value passed into it. The "amount" variable is immediately set to 0, and then the value passed in is added to amount (which is 0), and returns. The following code could replace this function:
public static int cookieJar(int addCookies){
return addCookies;
}
The above code will return an equivalent output to the given code.
Notice, the function is not dependent on any previous call, so the value for each is unique to the call itself, i.e., cookieJar(22) returns 22 and cookieJar(7) returns 7.
So, C. 22 would be correct.
Cell address $A$4 in a formula means it is a ___________. *
A. All of the above
B. Mixed cell reference
C. Relative cell reference
D.Absolute cell reference
Answer:
The answer to this question is given below in the explanation section
Explanation:
Cell address $A$4 in a formula means it is an Absolute Cell Reference.
Absolute cell reference does not change when you copy the formula to other cells. when the $ symbol added in the front of the column and row, makes it absolute. It stops the row and column numbers from changing when you copy to other cells. The given $A$4 cell address contains the value in column A and row 4. It does not change the value when you copy the formula that has mentioned ($A$4) into other cells. For example, if you have value 10 at row 4 and column A. Then you multiple column B with A4 cell value and you want that A4 value will not change while copying formula from C1 to C10. You can use in column C1 as =B1*$A$4. Then you copy the formula to cell 10. The value of $A$4 will not change.
while the other options are not correct because:
In the relative cell reference values get changed in the formula, while in the mixed cell reference you can either locked the row or column while the row or column changes when the formula is copied respectively.

Justify Alignment
When you click the Justify button, it displays four options, justify, justify low, justify high and justify medium. You need to select only the justify option. The difference between these options is that low justify creates little space between two words, medium creates a more space than low justify and high creates maximum space between two words to justify the text.
Answer:
There are four main alignments: left, right, center, and justified. i think i answered this correct but easier to understand
Given positive integer num_insects, write a while loop that prints that number doubled up to, but without exceeding 100. Follow each number with a space.
Sample output with input: 8
8 16 32 64
Here's what I havenum_insects = 8 # Must be >= 1print(num_insects, '', end='')while num_insects <= 100 : num_insects = num_insects * 2 print(num_insects,'', end="")This code prints the number 128 even thought the loop is set to end after 100? Why is that?
Answer:
The while loop is executed one more time when num_insects is 64. It gets doubled and 128 gets printed. Then the while loop is not executed anymore since 128 exceeds 100.
So the reason you see 128 is because the multiplication by 2 happens inside the loop before you print. You enter it with 64, but by the time you get to the print statement, it was already multiplied.
The solution is to switch the print and the multiply:
num_insects = 8 # Must be >= 1
while num_insects <= 100 :
print(num_insects,'', end="")
num_insects = num_insects * 2
This has one added advantage that the very first print statement outside the loop can be removed.

What is the value stored at x, given the statements:
int x;
x=3/(int)(4.5+6.4)
a. 0.3
b. 0
c. .275229
d. 3.3
e. None of these
Answer:
0.
Explanation:
Given
int x;
x=3/(int)(4.5+6.4)
Required
What is x?
The first line of the code segment declares x as integer. This means that, it will only hold non decimal numbers.
With the above explanation, options (a), (c) and (d) can not be true.
Solving further:
x=3/(int)(4.5+6.4)
The computer evaluates the denominator as:
x=3/(int)(10.9)
The denominator is then converted to an integer. So, we have:
x = 3/10;
3/10 = 0.3 but
Recall that: x will only hold non decimal numbers.
So:
x = 0;

Required:
a. How many bits do we need to borrow from the host portion?
b. List the lowest and the highest IP address of the first usable subnet.
c. How many usable hosts are there in total before and after subnetting?
Answer:
A. 6 bits
B. lowest IP address is 10.10.0.1 and the highest IP address is 10.10.3.254
C. total number of usable hosts before subnetting = 65534
total number of usable hosts after subnetting = 65408
Explanation:
The IP address 10.10.0.0 with the subnet mask 255.255.0.0 is a class B address with 16 bits of the network address portion and 16 bits of the host portion.
To subnet the address to use 62 subnets (and to reduce the host IP address wasted) 6 bits are borrowed from the host portion of the address to give 2^6 = 64 subnets with two usable host addresses.
The first network address is 10.10.0.0 and the first usable host address of the subnet is 10.10.0.1 making it the lowest address, while the broadcast address is 10.10.3.255 and the address before it becomes the higher address in the network which is 10.10.3.254
The number of usable host of the network before subnetting is 2^16 -2 = 65534, while after subnetting is (2^(16-6) - 2) x 64 = 65408.
If an exception is thrown, it is passed to a block of code that can ____, which means to receive it in a block that can handle the problem.
Answer:
Catch the exception.
Explanation:
In Computer programming, an exception can be defined as an unprecedented error or event that occurs unexpectedly while a computer software application or program is running. Thus, when this exception occurs while a software program is running, it would affect its flow.
However, if the software program is able to handle and process unprecedented error or event that occured unexpectedly, it would continue to run but if it cannot handle it, the software program will force quit.
In Java programming language, exception class such as IOException, UserException, TimeoutException, and exception subclass such as CharacterCodingException, FileNotFoundException etc may be thrown when a software program encounters an unexpected error or event.
A software program that is properly coded or well-written is able to check for exceptions and appropriately handle the exceptions (unexpected errors) so as to prevent the software program from crashing or forced to quit.
This ultimately implies that, when an exception is thrown using a try clause or throw statement as it occurs, it is caught by a block of code in the software program.
Hence, if an exception is thrown, it is passed to a block of code that can catch the exception, which means to receive it in a block that can handle the problem.

Explanation:
The python program gets the list of dictionaries of the users in a company and returns the user names and their roles. The code is defined as a function and is executed when the function is called.
Can race condition happen in monolithic memcached.
a. True
b. False
Answer:
True
Explanation:
It is TRUE that race condition happens in monolithic Memcached. This is evident in that in a python language, where Memcached "gets" and "set" function tends to turn to a race condition if for example the two functions are used together to accomplish similar things like locking given that it is not atomic.
Hence, in this case, the correct answer is TRUE
It should be noted that a race condition cannot occur in monolithic memcached. Therefore, it's false.
A race condition simply means when two threads are able to access a shared variable at a particular time.
In such a case, the first thread and the second thread will perform their operations on the value and they'll race in order to see the thread that can write the value last row of the variable that's shared. A race condition
cannot occur in monolithic memcached. Therefore, it's false.

Your company is designing a multi-tenant application that will use elastic pools and Azure SQL databases. The application will be used by 30 customers.
You need to design a storage solution for the application. The solution must meet the following requirements:
✑ Operational costs must be minimized.
✑ All customers must have their own database.
✑ The customer databases will be in one of the following three Azure regions: East US, North Europe, or South Africa North.
What is the minimum number of elastic pools and Azure SQL Database servers required?
Answer:
The minimum number of elastic pools and Azure SQL Database servers required is:
three elastic pools and one Azure SQL Database server.
Explanation:
The above will ensure that the Azure regions of East US, North Europe, or South Africa North are grouped into their three elastic pools. Since cost minimization must be achieved, at the same time, one Azure SQL Database server will be enough to manage the 30 databases required, with one for each customer. Creating more than one Database server will increase the operational costs.

A certain instructor assigns a 50-point problem and calculates an integer score 0-50 and assigns a letter grade according to the scale 40 - 50 is an A, 30 - 39 is a B, 20 - 29 is a C, 10 - 19 is a D and 0 - 9 is an F. Write a Python function called letter_grade which takes one argument, an integer, and RETURNS the appropriate letter grade.
Answer:
Following are the code to this question:
def letter_grade(x): #defining a method letter_grade that accepts one parameter
if x>=50 and x<=40:#defining if block that check value of x greater than 50 and less than 40
print("A")#print value
if x>=30 and x<=39:#defining if block that check value of x greater than 30 and less than 39
print("B")#print value
if x>=20 and x<=29:#defining if block that check value of x greater than 20 and less than 29
print("C")#print value
if x>=10 and x<=19:#defining if block that check value of x greater than 10 and less than 19
print("D")#print value
if x>=0 and x<=9:#defining if block that check value of x greater than 0 and less than 9
print("F")#print value
letter_grade(30) #calling the method letter_grade
Output:
B
Explanation:
In the above Python code, a method "letter_grade" is declared, that accepts an integer variable in its parameter, and defined the multiple if block to check the given value, which can be defined as follows:
In the first, if block, it checks the value of x greater than 50 and less than 40 , if the condition is true it will print the value "A".In the second, if block, it checks the value of x greater than 30 and less than 39, if the condition is true it will print the value "B".In the third, if block, it checks the value of x greater than 20 and less than 29, if the condition is true it will print the value "C". In the fourth, if block, it checks the value of x greater than 10 and less than 19, if the condition is true it will print the value "D".In the fifth, if block, it checks the value of x greater than 0 and less than 9, if the condition is true it will print the value "F".And at the last it call the method.

Write a program that keeps track of a simple inventory for a store. While there are still items left in the inventory, ask the user how many items they would like to buy. Then print out how many are left in inventory after the purchase. You should use a while loop for this problem. A sample run is below.
(CodeHS, PYTHON)
Answer:
STARTING_ITEMS_IN_INVENTORY = 20
num_items = STARTING_ITEMS_IN_INVENTORY
# Enter your code here
while num_items > 0:
print("We have " + str(num_items) + " items in inventory")
toBuy = int(input("How many would you like to buy?"))
if toBuy > num_items:
print("There is not enough in inventory")
print("Now we have " + str(num_items) + " left")
else: # ok to sell
num_items = num_items - toBuy # update
if num_items > 0: # only for printing
print("Now we have " + str(num_items) + " left")
print("All out!")
Explanation:
This allows Python to store the number of items in inventory after each purchase by subtracting how much is bought with the toBuy function by how much is left. This continues until num_items is no longer greater than zero. If what’s toBuy goes above the # of items left in inventory, then the “if toBuy > num_items” segment of the code comes into play by telling the user there’s not enough and re telling them how much is left and how much they’d like to buy. When the items in inventory is out, meaning the exact amount that’s left is purchased, then Python prints “All out!”
Following are the code to the given question:
Program Explanation:
Defining a variable "INVENTORY_ITEMS" that hold an integer value.Defining a variable "num" that holds "INVENTORY_ITEMS" value.In the next step, a while loop is declared that checks "num" value greater than 0.Inside the loop, "num and To_Buy" is declared and in the To_Buy it inputs value by user-end.In the next step, conditional statement is used that check "To_Buy" value and prints its value.At the last another conditional statement is used that checks num value, and print its value.Program:
INVENTORY_ITEMS = 20#defining a variable INVENTORY_ITEMS that hold integer value
num= INVENTORY_ITEMS#defining a num variable that holds INVENTORY_ITEMS value
while num > 0:#defining a while loop that check num value greater than 0
print("We have " + str(num) + " items in inventory")#print num value with message
To_Buy = int(input("How many would you like to buy?"))#defining To_Buy variable that inputs value
if To_Buy > num:#defining if block that check To_Buy value greater than num value
print("There is not enough in inventory")#print message
print("Now we have " + str(num) + " left")#print num value with message
else: # defining else block
num= num - To_Buy#using num variable that decreases num by To_Buy
if num> 0: #use if to check num greater than 0
print("Now we have " + str(num) + " left")#print num value with message
print("All out!")#print message
