For example, if the input is 98, the variable sum is 0 initially98%10 = 8 (% is modulus operator, which gives us the remainder when 98 is divided by 10).sum = sum + remainderso sum = 8 now.98/10 = 9 because in C language, whenever we divide an integer by another one, we get an integer.9%10 = 9sum = 8 (previous value) + 9sum = 179/10 = 0.So finally, n = 0, the loop ends; we get the required sum. And, in each iteration, the value of i is added to sum and i is incremented by 1. In both programs, the loop is iterated n number of times.
