check the macros in your code 

[Nayan Sharma]

What does macro mean?

Btw i read forums on keil and i found a solution and it did work, but ill have to check on proteus and simulate the code

The solution that i did was that i added the Hello.c file to my source folder and then compiled my program, i dont know how but it did work
Can you explain?
