Longer answer: A header file, by itself, is almost always useless. You need code to go with it. When you compile your code, it is typically automatically linked against the Standard C/C++ library. This library has been precompiled for you and you include things like cstdio, iostream, etc. to gain access to the various bits of functionality exported by the library. Header files are plain-text files. Go into your compiler's directory and look at some of them. You won't see a whole lot of code there (if any) - just function declarations, #defines, etc. designed for the preprocessor. -- Thomas Hruska CubicleSoft President Ph: 517-803-4197 *NEW* MyTaskFocus 1.1 Get on task.
