header in multiple .cpp files?
header in multiple .cpp files?
ok so here is my problem if i include gotoxy.h file to 1 .cpp fille it works fine but as soon as i try adding it to 2 files it gives me this error
gotoxy.h
Could some one help me? what did i miss? i am a newbie i haven't touched c++ in a while, schools over and i have TONS of free time but this kinda annoys me i am sure you can use one header file in multiple .cpp files right? so whats wrong :S

You have probably have a function for example, called blah() in one of your blah.cpp files and in one of your referenced headers theres another function called blah() so they clash?
Make base class with virtuals
nah its ok thanks you can close this i just tried to be more OOP and put the commands in the .h and the core of the commands in a attaches .cpp dono why i did not do that to start with thanks alot tho <3
