Question 7

A while loop can be nested inside a for loop and vice versa.

Accepted Answer

A) True 
 B)False

Question 8

When you use a while loop to compute the sum of several values, you should initialize the variables holding the sum to:

Accepted Answer

A)  0. 
B)  1. 
C)  NULL. 
D)  There is no need to initialize them. 
A)  0. 
B)  1. 
C)  NULL. 
D)  There is no need to initialize them.

Question 9

You have a for loop nested in a while loop in order to find prime numbers. The proper way is to set the flag to false before starting the for loop that checks for factors. Inside the for loop, set the flag to true when a factor is found. After the for loop terminates, check the value of the flag. If it is still false, no factors were found and the number is prime.

Accepted Answer

A) True 
 B)False

Question 10

Accepted Answer

A)  The sentinel value is the last input value. 
B)  The sentinel value is the first input value. 
C)  The sentinel value is the third input value. 
A)  The sentinel value is the last input value. 
B)  The sentinel value is the first input value. 
C)  The sentinel value is the third input value.
