Why am I getting an "identifier undefined" error?

Essentially I'm trying to read certain lines from a .txt file and I made this function:

//Function to read specific lines of .txt files


 std::fstream& GotoLine(std::fstream& file, unsigned int num)
    {
        file.seekg(std::ios::beg);
        for (int i = 0; i < num - 1; ++i) {
            file.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
        }
    
        return file;
    }

I made the function inside main.cpp and outside the main function at the bottom, so I made sure to prototype it before the main function as such:

 std::fstream& GotoLine(std::fstream& file, unsigned int num);

but when I try to use it inside the main function it gives an error saying: E0020: identifier "GoToLine" is undefined

This is how I use it inside the main function:

GoToLine(inFile, 8);

C++ is case sensitive

The error is simply because while calling the function you are calling GoToLine(inFile, 8); with a capital " T " whereas in function definition it is small " t "

std::fstream& GotoLine(std::fstream& file, unsigned int num);
