“For” Loops

A loop statement tells the computer to execute a set of instructions many times, and is controlled by the loop variable.

int sum, num;

num = 8;

sum = 0;

for ( int i = 0; i < num; i++ )

{

sum = sum + i;

}

repeat loop 8 times and

add 1 to i each time

The body of the loop is repeated. Values of i each time around the loop:

i is 0

i is 1

i is 2

. . .

i is 7

What is the value of sum at the end?
