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

The for loop body executes indefinitely if the loop condition is always ____________________.

What is the output of the following C++ code? num = 100; while (num <= 150) $\quad$ num = num + 5; cout << num << endl;

Which of the following is a repetition structure in C++?

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

The function eof is a member of the data type ____________________.

The function srand takes as input a(n) ____________________ int, which acts as the seed for the algorithm.

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

____ loops are called posttest loops.

What is the output of the following loop? count = 5; cout << 'St'; do { $\quad$ cout << 'o'; $\quad$ count--; } while (count <= 5);

Putting one control structure statement inside another is called ____________________.

A for loop is typically called a counted or ____________________ for loop.

What is the output of the following C++ code? count = 1; num = 25; while (count < 25) { num = num - 1; $\quad$ count++; } cout << count << " " << num << endl;

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

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

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

A do...while loop is a(n) ____________________ loop, since the loop condition is evaluated after executing the body of the loop.

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

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

What is the output of the following C++ code? int j; for (j = 10; j <= 10; j++) $\quad$ cout << j << " "; cout << j << endl;
