Example 1:
x = 1;
sum = 0;
while (x <= 3)
{
sum = sum + x;
x = x + 1;
}
//sum holds the value 6 after the while loop.
Example 2:
number = 1;
for (i = 1; i <= 4; i++)
{
number++;
}
//number holds the value 5 after the for loop. The loop will iterate four times (when i is 1, 2, 3, and 4). Number is incremented by 1 for each iteration. Therefore, number is 5 upon termination of the loop.
