C PLUS PLUS REFERAT SCOALA

A headerfile is a compilation of pre-made, commonly-used commands. They are probably located in the "INCLUDE"-directory where you keep your compiler. The most used header-files, when programming basic C, are STDIO.H (STandarD In Out) and CONIO.H (CONsole In Out). They contain most (if not all) of the commands you'll need while using this tutorial. To include a header file, so that you are able to use the commands it contains, use the "#include" command. An example of including CONIO.H is: #include "C:\QC\INCLUDE\CONIO.H" With some compilers you can include a headerfile without specifying the entire path. This works by putting brackets around the headerfile's name, like this: #include When the C-compiler compiles your program it has to know where to start. That's why at least one of your functions (NOOO! Don't scream! I'll explain functions later.) has to be named main. A function always has a pair of parantheses after the name, why I'll explain later. To mark the start and the end of a function we use {}, where { marks the start, and } marks the end. If we combine this with our old knowledge about #include we are now able to set up our first C-program:
