Question

Apply the Laws of Programming to transform the program given below into an equivalent progriam which contains not more than ane WHIlLE statement (and, of course, no FOR statement at all).

Answer 1

The task involves transforming a program with multiple loops into one with a single WHILE loop, implying a refactoring of FOR loops into WHILE loops without changing the program's logic.

Step-by-step explanation:

The question asks us to apply the laws of programming to transform a given program with multiple loop constructs into an equivalent program containing no more than one WHILE statement. In the context of programming, this usually means refactoring the code to remove FOR loops and replace them with WHILE loops while ensuring that the logic and functionality of the original program remain intact.One common technique to convert a FOR loop to a WHILE loop is to initialize the loop control variable before the loop, replace the FOR with a WHILE, and then increment or update the loop control variable within the body of the WHILE loop. The condition for the WHILE loop would mirror the condition from the FOR loop.

It is important to accurately translate the initialization, condition, and incrementation elements of the FOR loop to ensure that the refactored WHILE loop behaves identically. Making sure to maintain the flow of control and the logic of the original program is key to a successful transformation.
