Beginner C question: using variables, console closes immediately

I'm a complete beginner to programming C, so please bare with me here I'm using Code::Blocks v1.0 (on window$) with GCC. CODE #include <stdio.h> int main() { int this_is_a_number; printf( "Please enter a number: " ); scanf( "%d", &this_is_a_number ); printf( "You entered %d", this_is_a_number ); getchar(); } When I choose to start a new project and build it as a part of the project it runs fine. But when I build it as a standalone file and run it, console simply pops up and disappears. How do build and run it from a single c file instead of having it as a part of a project? Thanks!

Or you can run it from the command line, and avoid the problem all together! http://www.dreamincode.net/forums/showtopic30581.htm
