How can I get the sum of the numbers?

nekoxandu (13)
In this program you can type in any non-negative integer and it will go through the formulas inside the program and give you an output. the program runs perfectly fine if you want to compile and run it, but how can i find the sum of the numbers that are output? i tried adding a sum formula in the while loop, but it only added up the last two numbers.

You don't do anything with 'sum' not even intialization.

sum = 0;
...
sum += x; // After line 50
