Question

Because the for loop tests its Boolean expression before it performs an iteration, it is a ____________.

a. pretest loop
b. pseudo loop
c. posttest loop
d. infinite loop

Answer 1

a. pretest loop

Step-by-step explanation:

The for loop is a pretest loop because it tests its Boolean expression before it performs an iteration. The structure of a for loop is as follows:

```

for (initialization; boolean expression; update) {

// loop body

}

```

The initialization statement is executed before the loop starts, and the Boolean expression is tested before each iteration of the loop body. If the expression is true, the loop body is executed, and then the update statement is executed. The process repeats until the Boolean expression is false.

Because the Boolean expression is tested before each iteration, a for loop is useful in situations where you know in advance how many times you want to execute a certain set of statements. The initialization and update statements allow you to control the iteration process and modify loop variables as needed.
