CH5 Quiz

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

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

Consider the following code. (Assume that all variables are properly declared.) cin >> ch; while (cin) { cout << ch; cin >> ch; } 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 j, sum, and num are int variables, and the input is 26 34 61 4 -1. What is the output of the code? sum = 0; cin >> num; for (int j = 1; j <= 4; j++) { sum = sum + num; cin >> num; } cout << sum << endl;

Suppose sum and num are int variables, and the input is 18 25 61 6 -1. What is the output of the following code? sum = 0; cin >> num; while (num != -1) { sum = sum + num; cin >> num; } cout << sum << endl;

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

What executes immediately after a continue statement in a while and do-while loop?

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

What is the output of the following C++ code? num = 10; while (num > 10) num = num - 2; cout << num << endl;

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

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

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

Which of the following statements generates a random number between 0 and 50? a. srand(time(0)); num = rand() % 50; c. srand(time(0)); num = rand()50; b. srand(time(10)); num = rand()/50; d. srand(time(10)); num = rand() % 50;

____ loops are called posttest loops.
