Help needed #ifndef HELPER_H

[desert wave]

Hi im having a hard time with trying to get my school lab to work for me the issue is coming from #ifndef HELPER_H it's giving me error codes: LNK2019, and LNK1120. I'm using Microsoft Visual Studio and the language is C++.

This is what's in my .h file

#ifndef HELPER_H
#define HELPER_H
#include <iostream>
#include <cstdlib>
#include <ctime>
#include <bitset>
#include <vector>
#include <limits>

namespace Helper {
    int GetValidatedInt(const char* strMessage, int nMinimumRange = 0, int nMaximumRange = 0);
    int getRandoInt(int min, int max);
    int whatsUrOrder(const std::string& menuName, const std::vector<std::string>& menuList);
    void DisplayIntForms(int value);
    void InputBufferBGone();
}

#endif // !HELPER_H

Can you share the linker errors?

Generally a linker error is going to come from:

Declaring (and using) a function in a .h file but not implementing it in the .c/.cpp file, or
Declaring and implementing the function properly but not telling your compiler to compile the .c/.cpp file

You can get a LNK2019 if you didn't define a function that you declared, by any chance would you mind sending the rest of your code? There doesn't seem to be any linker errors directly in the header file

Or if you send your project or .sln file/folder I'd be glad to just look through and run it on my computer
