Given 'N' , compute the Sum of natural numbers till N

Given a number 'N' , you have to compute the sum of natural numbers from 1,2,3,4,....N (inclusive).



For Example:
If N=10, 
then SUM = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10
                 = 55  



Implementation:


#include<stdio.h> int main() { int limit,i,sum=0; printf("Enter the range to calculate sum of natural numbers"); scanf("%d",&limit); for(i=1;i<=limit;i++) sum+=i; printf("Sum=%d",sum); return 0; }

Output:

Enter the range to calculate sum of natural numbers
10
Sum=55
