Inside the parentheses of a while loop, what normally occurs

The correct answer is: "An expression is evaluated."

Explanation:

Inside the parentheses of a while loop, there is a conditional statement (or expression) that is evaluated. For example:

int a = 10;

while(a>0) {

cout << a << endl;

a--;

}

In the above snippet of code, you can see that inside the parentheses of a while loop, there is a condition (or expression) a > 0. It is evaluated in every iteration. If that condition meets (or true), the block of while loop will be executed. Hence, the correct answer is "an expression is evaluated."
