Sum of array elements using Functions

Description:

Write a C program to find the sum of the elements in an array. Input Format: Input consists of n+1 integers. The first integer corresponds to n , the size of the array. The next n integers correspond to the elements in the array. Assume that the maximum value of n is 15. Output Format: Refer sample output for details. Test Case 1 Input (stdin) 5 2 3 6 8 1 Expected Output 20 Test Case 2 Input (stdin) 5 2 3 4 5 1 Expected Output 15

Program :

#include<stdio.h>

int main(){

  int n,i,a[20],sum=0;

  scanf("%d",&n);

  for(i=0;i<n;i++)

  {

    scanf("%d",&a[i]);

    sum=sum+a[i];

  }

  printf("%d",sum);

  return 0;

}
