| | Historically, - C++ was derived from C. - In C, everything was an int unless specified otherwise (there was no void), so it was natural for main to return int. - C programs were originally developed for command line use, and using a command line interpreter which was far more …  |

| | Mixing input methods is always a disaster waiting to happen, especially when you mix those which attempt to parse the input with those which just read the input. The different ways in which white-space and newlines get treated will catch you out. Read a whole line into a string (preferably … |

No. [url]http://www.catb.org/~esr/faqs/smart-questions.html#prune[/url] How about posting something useful like - which OS and compiler - your example program which shows that error.
