This program illustrates the more practical example of application of C-loops discussed in previous lession. This program calculates the sum of first n natural numbers. Complete source code and output of program is given here..

**Source Code**`1: // summation of first n natural numbers`

2: #include<stdio.h>3:`4: int main(){`

5: int i, sum = 0; //for storing sum, initially must be zero`6: int n;`

7: printf("Enter the number: ");8: scanf("%d",&n);9:`10: for(i = 0; i <=n; i++){`

11: sum = sum + i;12: }13:14: printf("The sum of first %d natural number is %d\n\n", n,sum);`15: return 0;`

16: }17:

**Output**
