While this expression evaluates true, the statements repeat. Like other C constructions when more than a single statement is repeated, they all must be enclosed in braces.

Therefore, the loop's condition must be initialized before the loop starts as a separate statement. Further, the loop's statements must contain its exit strategy, something that alters the condition the while statement evaluates and eventually terminates the loop. The while loop in this exercise file repeats 10 times. Variable a is initialized to zero at line seven. This is the setup. The loop's statements repeat as long as the value of variable a is less than 10. At line 11, variable a is modified, which…
