• Test Case 1

  
  Input (stdin)

  5
  
  2 3 6 8 -1
  
  

  Expected Output

  sum=19

• Test Case 2

  
  Input (stdin)

  5
  
  -1 -2 -3 -4 -5
  
  

  Expected Output

  sum=0

• Program

• #include <stdio.h>
  int main()
  {
    int num,a[100],sum=0,i;
    scanf("%d",&num);
    for(i=0;i<num;i++)
      scanf("%d",&a[i]);
    for(i=0;i<num;i++)
    {
      if(a[i]>=0)
        {
          sum=sum+a[i];
        }
    }
    printf("sum=%d",sum);
    return 0;
  }
