Hi guys! Can anyone help me? Im a new to this site and C++ environment. Im running a Microsoft Visual C++ express 2010 and I write a code in 3 separate files. 1 of them is a header file with an extention .h. and 2 of them are .cpp files. I have defined function prototype in the header file and its implementation in .cpp file. Then i execute this code in "int main" function which i have defined into the 3rd separate file. And while compiling it shows a linker error. i think the problem is the location of those many files. How shall i place those files to make the main program execute???? How can i link those files and where to execute the application Thank you
