In this section you will learn how to write the C Program to find the sum of N Natural Number.
For Eg. Find the sum of first 5 natural number
1+2+3+4+5 = 15
Now lets see the C Program to find the sum of N Natural Number
Program
/* Exp No 3: display natural number and find sum */
#include <stdio.h>
int main()
{
int n,i,sum=0;
printf("Enter How many terms to be display\n");
scanf("%d",&n);
/* display series and find sum */
for(i=1; i<=n; i++)
{
printf("%4d",i);
sum = sum+i;
}
printf("\n Sum of natural number = %d \n",sum);
return 0;
}
Output :-
