thank s

What have you tried?

Get rid of void main: SourceForge.net: Void main - cpwiki
Start putting the names of your arguments in your prorotypes: SourceForge.net: Do not remove parameter names - cpwiki

You should only have one loop in main :

Code:

---

While there is still input
{
  get next input
  if (input is operator)
  {
      pop two items
      perform operation on those items
      push result
  }
  else if input is number
      push input
  else
      error
}
