Explanation / Answer

Question: If Number = 4, what is the range of possible numbers that can result from the following? (Note, this question has 2 parts; you must answer each part correctly to receive full marks. Enter only the numbers in the space provided.)

          Floor(Random() * 10) + Number

The range starts at  .

The range ends at  .

Answer: The range starts at 4 and ends at 10.

Question: Write a random generator statement that produces random integers in the following range; store the result in a variable called Range. (Do not include spaces in your answer.)

1 through 4

Answer: Floor(Random() * 4) + 1

Question: The _____________ function takes a string or a string variable inside the parentheses and returns the number of characters in that string.

Answer: Length_Of function returns the length or we can say number of characters in that string.

Question: If Number = 25, what would be the result of the following conditional statement? True or false?

Sqrt(Number) == Floor(Sqrt(Number))

True

False

Answer: Sqrt(Number) which is sqrt(25) i.e 5

Now Floor(sqrt(25))

Floor(5) and this will return 5

Hence both are equal so True.

Question: If Number is an integer value, what would be displayed as a result of the following assignment? (Note: if there are any spaces, it is assumed to be one space.)

Set Number = Length_Of(" ")

Write Number

Answer: The value will be 0 as this is an empty string.

Question: If Number = 64, what would be the result of the following conditional statement? True or false?

Floor(Sqrt(Number/2)) == Sqrt(Floor(Number/2))

True

False

Answer: First let’s see sqrt(Number/2) which is sqrt(64/2)

Sqrt(32) which is 5.6568 and now if we take floor of this value i.e floor(5.6568) then this will return 5 (smaller nearest number or equal to it). This means

Floor(Sqrt(Number/2)) = 5

Now Sqrt(Floor(Number/2))

Sqrt(Floor(64/2))

Sqrt(Floor(32)) //number nearest smaller or equal to

Sqrt(32)

= 5.6568

5 = 5.6568 which is false.

Question: If Number = 7,  what would be the result of the following conditional statement? True or false?

Sqrt(Number) == Int(Sqrt(Number))

True

False

Answer: sqrt(7) will get the square root of the number 7 which is 2.6457 and if we pass this value to Int then it will only return the real part of it and leaves the decimal part hence Sqrt(Number) == Int(Sqrt(Number)) are not equal so false.

Question: The ___________ allows for output from Print statements to occur on a new line.

Numbers that form an unpredictable sequence in which each number is equally likely to occur are called __________ numbers.

Answer: will allow the output to be printed in next line.

Numbers which are unpredictable are called Random numbers.

Question:If Num1 = 5.6 and Num2 = 3, what value would be displayed as a result of the following assignment?

Set Number = Floor(Num1 * Num2)

Write Number

Answer: Floor function returns the value less than or equal to the parameter passed to it.

Now here we are dividing num1 by num2 which is 5.6/3 = 1.866667 or we can say 1.87. Now if we pass this to floor it will return 1 as the nearest less number to 1.87 is 1.

Question: The following random generator code Floor(Random()*6) produces the numbers   through . (Note, this question has 2 parts; you must answer each part correctly to receive full marks. Enter only the numbers in the space provided.)

Answer: Here we can see the given equation as Floor(Random() * Number) + 0. Hence the range starts at 0 and range ends at 6

Question: If Num1 = 3.2 and Num2 = 5, what value would be displayed as a result of the following assignment?

Set Number = Int(Num2 - Num1)

Write Number

Answer: Here we have Num2 = 3.2

And Num2 = 5

Now Num2-Num1

= 5-3.2

= 1.8

And now as we have passed this to int which takes only int value and not the decimal value. So the value will be 1.

Question: If Number = 4, what is the range of possible numbers that can result from the following? (Note, this question has 2 parts; you must answer each part correctly to receive full marks. Enter only the numbers in the space provided.)

Floor(Random() * Number)

The range starts at  .

The range ends at  .

Answer: Here we can see the given equation as Floor(Random() * Number) + 0. Hence the range starts at 0 and range ends at 4.

Question: If Number = 6, what is the range of possible numbers that can result from the following?

Floor(Random() * Number) + 3

The range starts at  

The range ends at  .

(Note, this question has 2 parts; you must answer each part correctly to receive full marks. Enter only the numbers in the space provided.)

Answer: Here the minimum range or we can say range starts at 3 and range ends at 6.

Question: The random generator code Floor(Random()*6) produces the numbers  through . (Note, this question has 2 parts; you must answer each part correctly to receive full marks. Enter only the numbers in the space provided.)

Answer: This will produce random number between 0 to 6.

Question: It's possible to __________ out of a loop if the user has entered an incorrect value that would cause an error or a problem within the loop, or if the user has entered a required response end the program can continue without further iterations of the loop.

Answer: break, which makes it possible to get out of the loop or we can say break the loop.

Question: If Num = 4.22, what value would be displayed as a result of the following assignment?

Set Num = Ceiling(Num)

Write Num

Answer: Ceiling(4.22)

This will return 5 as Ceiling function returns the value equal to or nearest greater value.

Question: If Number = 3.5, what would be the result of the following conditional statement? True or false?

Floor(Number*Number) == Number*Number

True

False

Answer: Here the value of number is 3.5

Number * Number = 3.5 * 3.5

                                = 12.25

Now Floor(Number*Number) = Floor(3.5*3.5)

                                                      = Floor(12.25)

                                                = 12 (as Floor function returns the value equal to or nearest less than to it value).

Hence Floor(Number*Number) = Number*Number

12 = 12.25 is false

Question: If Num1 = 5.6 and Num2 = 3, what value would be displayed as a result of the following assignment?

Set Number = Floor(Num1 / Num2)

Write Number

Answer: Floor function returns the value less than or equal to the parameter passed to it.

Now here we are dividing num1 by num2 which is 5.6/3 = 1.866667 or we can say 1.87. Now if we pass this to floor it will return 1 as the nearest less number to 1.87 is 1.

Question: If Num = 6.89,  what value would be displayed as a result of the following assignment?

Set Num = Ceiling(Num)

Answer: The ceiling function returns the smallest near to or equal to the parameter passed to the function and here we have passed 6.89 and the nearest number is 7.

Question: If Number is an integer value, what would be displayed as a result of the following assignment? (Note: if there are any spaces, it is assumed to be one space.)

Set Number = Length_Of("Good-bye!")

Write Number

Answer: It will calculate length of the string which is 9 hence the value of the Number is 9.
