Question

Consider the following two code segments. In both, assume that n is an integer variable that has been declared and initialized. Segment 1 int prod = 1; int i; for (i = 2; i <= n; i++) { prod *= i; } System.out.println(prod); Segment 2 int prod = 1; int i = 2; while (i <= n) { prod *= i; i++; } System.out.println(prod); For which integer values of n do these code segments print the same result?

Answer 1

Answer:

For every value of n.

Explanation:

In code segment 1 it uses for loop to store the product of integers from 2 to n in variable product it does that by using a for loop after that printing the product.

In the other code segment the same thing is done the only difference is that it uses a while loop instead of for loop to find the product and then printing the product.

So the result will be same for every value of n.
