A preprocessor is a program that translate some text input into data that will be used by another program.
In C/C++ the preprocessor reads the lines that start with '#' and translate the source file into source code that the C/C++ compilator will fully understand and can compile.
For example #include myfile.h would be replaced by the content of the actual header file.
