In this program, we will ask the user to provide the minimum value and a maximum value range to be added and find integers divisible by 5 and a total of those integers.

To find integers divisible by 5, we will first start a for loop with variable **i**, which is the minimum value **N1 **provided by the user and will increase it using **i++ **until the value of **i **is equal to the maximum value which is **N2.**

Inside the for-loop, we will use **if-else **condition to check if the provided value of **i %5 **gives result in zero or not. If it is zero it means the value is divisible.

We will add 1 in a variable **COUNT **whose initial value was zero. With every true condition, count will work as follows –

- count = 0
- count = count ++ (current value is 1)
- count = count ++ (current value is 1+1 = 2)
- count = count ++ (current value is 2+1 = 3)

Also, we will add the value of integer to another variable **SUM**. It will give us the total sum of integers which are divisible by 5. For example, 5,10,15 are divisible by 5. So for them, it will work as follows –

- sum = 0
- sum = sum + i (current value of i is 5 so , sum = 0 + 5 = 5)
- sum = sum + i (current value of i is 10 so , sum = 5 + 10 = 15)
- sum = sum + i (current value of i is 15 so , sum = 15 + 15 = 30)

## Here is the code Find the Number of Integers Divisible by 5 and their sum

```
void main()
{
int i, N1, N2, count = 0, sum = 0; /* declares count, sum and two variables as integer */
clrscr();
printf ("Enter the value of N1 and N2\n"); /* user gives the value for lower and upper range */
scanf ("%d %d", &N1, &N2);
/*Count the number and compute their sum*/
printf ("Integers divisible by 5 are\n");
for (i = N1; i < N2; i++)
{
if (i%5 == 0)
{
printf("%3d,", i); /* using mod operator check the number is divisible by 5 */
count++;
sum = sum + i; /* add the numbers divisible by 5 to sum variable */
}
}
printf ("\nNumber of integers divisible by 5 between %d and %d = %d\n",
N1,N2,count);
printf ("Sum of all integers that are divisible by 5 = %d\n", sum); /* displays the output of program */
}
```
