Suppose sum, num, and j are int variables, and the input is 4 7 12 9 -1. What is the output of the following code?

Assume that all variables are properly declared. The following for loop executes 20 times.

What is the initial statement in the following for loop? (Assume that all variables are properly declared.)

In a counter-controlled while loop, the loop control variable must be initialized before the loop.

In a while and for loop, the loop condition is evaluated before executing the body of the loop. Therefore, while and for loops are called ____________________ loops.

The ____ statement can be used to eliminate the use of certain (flag) variables.

Which executes first in a do...while loop?

What is the output of the following C++ code?

A loop that continues to execute endlessly is called a(n) ____ loop.

A semicolon at the end of the for statement (just before the body of the loop) is a(n) ____________________ error.

What is the output of the following C++ code?

Consider the following code. This code is an example of a(n) ____ while loop.

In ____ structures, the computer repeats particular statements a certain number of times depending on some condition(s).

Suppose sum and num are int variables, and the input is 18 25 61 6 -1. What is the output of the following code?

A(n) ____-controlled while loop uses a bool variable to control the loop.

Which of the following statements generates a random number between 0 and 50?

____ loops are called posttest loops.

The control statements in the for loop include the initial statement, loop condition, and update statement.

When a continue statement is executed in a ____, the update statement always executes.

In the case of the sentinel-controlled while loop, the first item is read before the while loop is entered.
