write a program to Print the sum of first n natural numbers.

// program to Print the sum of first n natural numbers.

#include<stdio.h>


int main()


{

int sum=0, n;

printf("enter any number\n");

scanf("%d", &n);

for(int i=1; i<=n; i++){

sum = sum+i; //it will work like 1+2+3+4+5+6=21

}

printf("sum of first n natural numbers = %d\n", sum);

return 0;

}

Output :

enter any number

6

sum of first n natural numbers = 21
