Tiny C Compiler

A very small (275kb) and fast C compiler. Available for Linux & Windows version.
For windows version, just download and uncompress the zip file.
Create a simple C program, example (hello.c)
#include <stdio.h>
main()
{ printf ("Hello world!");
return 0;
}
compile using this command: tcc hello.c
execute your program : hello <enter>

Note : too bad I can't compile a C++ program with this.
