Write a C program to find the sum of first n natural numbers using recursion. The user inputs the value of n.

This is what I have but my program keeps crashing. Please comment new code:

#include<stdio.h>
#include<conio.h>

int add(n);

int main()
{

int n;

printf("Enter an positive integer");
scanf("%d",n);

printf("Sum=%d",add(n));

return 0;
}

int add(int n)
{

if(n!=0)

return n + add(n-1); /* recursive call */

}
