How to prevent multiple definitions in C?

Question

I\'m a C newbie and I was just trying to write a console application with Code::Blocks. Here\'s the (simplified) code: main.c:

#include 
#incl         


        

Answer 1

I had similar problem and i solved it following way.

Solve as follows:

Function prototype declarations and global variable should be in test.h file and you can not initialize global variable in header file.

Function definition and use of global variable in test.c file

if you initialize global variables in header it will have following error

multiple definition of `_ test'| obj\Debug\main.o:path\test.c|1|first defined here|

Just declarations of global variables in Header file no initialization should work.

Hope it helps

Cheers
