What does the following fragment of code display? What do you think the programmer intended the code to do, and how would you fix it? int product = 1; int max = 20; for (int i = 0; i <= max; i++) product = product * i; System. out. println("The product is " + product);

0

Explanation:

Given the code segment:

       int product = 1;        int max = 20;        for (int i = 0; i <= max; i++)            product = product * i;        System.out.println("The product is " + product);

Since the counter i in the for loop started with 0, and therefore product * i will always be 0 no matter how many rounds of loop to go through.

The code is likely to perform factorial calculation. To do so, we need to change the starting value for the counter i to 1.

       int product = 1;        int max = 20;        for (int i = 1; i <= max; i++)            product = product * i;        System.out.println("The product is " + product);
