empty file

[pronoob?]

while im working on a project everythings fine. in order to test a code piece i opened a new empty file and put the code then "build and run" but the code in empty file is not compiled. instead the one in main project is compiled. I'm doing C programming. Why is it not compiled? any other way to test a code pice away from main proj? Thanks in advance.

Let me ask you a similar question: I have two files the one works, the other not. Why?

See how little information you provided? What answer do you expect?

As a guess, you have a project open, and the file that is not compiling is not part of the active target (and maybe not even part of the project).
But this is just a guess; you have provided very little information.
