        because we have to print sum in output. So , in for loop we traverse all element and add it in variable names sum and display it eg - we have array={1,2,3,4,5} when we run loop from i=0 it add a[0] (i.e - 1) in sum variable , similarly we run it till i=4 (i.e -5) . so sum=1+2+3+4+5

        i'm not good in explaining but hope it helps :)

    int main() {

    /* Enter your code here. Read input from STDIN. Print output to STDOUT */   
    int i,a[10]={16,13,7,2,1,12};
 int n=6,sum=0;



      for(i=0;i<n;i++)
     {
      sum+=a[i];
                }
                printf(" %d",sum);
                return 0;

                }
