Write a C program to find the number of and sum of all integers greater than 50 and less than 300 that are divisible by 9 using function.

#include <stdio.h>
#include <conio.h>
int div(int n);
int main()
{
    int i,sum=0,m;
    clrscr();
    for(i=51;i<300;i++)
    {
        m=div(i);
        sum=sum+m;
    }
    printf("\n\nSum of these numbers is: %d",sum);
    getch();
}

int div(int n)
{
    if(n%9==0)
        return(n);
    else
        return(0);
}
