Here is source code of the C program to calculate the number of integers divisible by 5. The C program is successfully compiled and run on a Linux system. The program output is also shown below.
* C program to find the number of integers divisible by
* 5 between the given range num1 and num2, where num1 < num2.
* Also find the sum of all these integer numbers which are divisible
* by 5 and display the total.
int i, num1, num2, count = 0, sum = 0;
printf("Enter the value of num1 and num2 \n");
scanf("%d %d", &num1, &num2);
/* Count the number and compute their sum*/
printf("Integers divisible by 5 are \n");
for (i = num1; i < num2; i++)
if (i % 5 == 0)
sum = sum + i;
printf("\n Number of integers divisible by 5 between %d and %d =
%d\n", num1, num2, count);
printf("Sum of all integers that are divisible by 5 = %d\n", sum);
$ cc pgm18.c $ a.out Enter the value of num1 and num2 12 17 Integers divisible by 5 are 15, Number of integers divisible by 5 between 12 and 17 = 1 Sum of all integers that are divisible by 5 = 15
