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? |
