### Example Using the While Statement

In the following program, `item[index]` triples each time the value of the expression `++index` is less than `MAX_INDEX`. When `++index` evaluates to `MAX_INDEX`, the while statement ends.

>     #define MAX_INDEX  (sizeof(item) / sizeof(item[0]))
>     #include <stdio.h>

>     int main(void)
>     {
>        static int item[ ] = { 12, 55, 62, 85, 102 };
>        int index = 0;

>        while (index < MAX_INDEX)
>        {
>           item[index] *= 3;
>           printf("item[%d] = %d\n", index, item[index]);
>           ++index;
>        }

>        return(0);
>     }
