1>Trianglesmain.obj : error LNK2019: unresolved external symbol "public: void __thiscall Equilateral::printEqui(void)const " (?printEqui@Equilateral@@QBEXXZ) referenced in function _main

Getting this error message when compling/linking class, header and source files for class equilateral. Using MS Visual Studio latest version. ??

You don't appear to have implemented the class method void Equilateral::printEqui() const.

I have these functions declared in the .h file and defined in the .cpp file yet it appears system canot fnd them?

and ideas

[kbw]

There's nothing more anyone can conclude from the information you've provided.

A guess:

Maybe the function declaration and definition differ in the trailing const. In C++, these are two different functions:

void Equilateral::printEqui() const;
void Equilateral::printEqui() ;

I am guessing you might have had:

class Equilateral {
  public:
     void  printEqui() const;

};

void Equilateral::printEqui()  { // missing const

}

As kbw says, show us the code :+)

By the way, you don't have to use void for functions with no arguments, that is a C thing:

Equilateral::printEqui(void)const
