Hi i am getting error LNK2001: unresolved external symbol_function name
where these functions are called in the main function.
I think you have not linked some library. Also search on MSDN (google) regarding error LNK2001 and relate it's explanation with your code. You will find the solution.
Are these your functions? If so, you have not included the function definitions in your build. If they are library functions you need to add the appropriate library to the list of linker dependencies.
