    keeping track of values

    if you have a loop that asks for the user to input a value and the loop doesn't end until the sentinal, how can you keep track of all the values entered and add them together?

    A sum and an input?

    Code:
       sum = 0;
       while ( scanf("%d", &d) == 1 )
       {
          sum += d;
       }
