A programmer has written the C# program in Figure 5 to add up the numbers between one and five - AQA - GCSE Computer Science - Question 14 - 2021 - Paper 1

The correct modification is given in option B:

int total = 0;
int product = 1;
for (int number = 1; number < 6; number++)
{
    total = total + number;
    product = product * number;
}
Console.WriteLine(total);
Console.WriteLine(product);

This program calculates the sum of numbers from 1 to 5 with total and their product with product. This meets the requirement to add and multiply the numbers between one and five.
