I was just hunting around the answered questions in the C topic area and came across this one which you answered. The que. was accepted on 4-19-98. Out of curiosity and to learn from it, as I am learning this topic, I compiled and ran the program. It compiles with no errors, but when I run it, nothing happens. Can you tell me why? Can you show me how to run it with results? i.e., do you have to put some printf's in certain locations to see the results? Thank you; this would be a great help.
