    cin.get();

Saye stot() is undeclared, and
"no match for call to (whateyva) (int, int)"
I have absolutely no idea.
I've checked my sources and it appears my syntax is ok. Any ideas?

I noticed two problems:

wuse.cpp line 20: I don't think you can call a constructor that way; I believe you have to call it when creating the instance or not at all.

wuse.cpp line 29: stot() is not a global function, so you have to call it like so: mood.stot();
Putting it inside of a cout statement is also wrong since the function does the output itself and does not return a value.

WinMain is the entry point to a windows GUI program. The code you have shown int main() is the entry point to a windows CONSOLE program.

I think you have got your windows types mixed up.

Fixed it! Thanks.

#include "w.h"
using namespace std;

    do
    {
    int count = 0;
    cout << "Anything ";
    if(count > 0)
    cout << "else ";
    count++;
    cout << "happen to you today? [y/n] > ";
    char occur;
    cin >> occur;
    occur = tolower(occur);
    if(occur == 'n')
    break;
    
    cout << "Good [g] or bad [b]? >";
    char ooo;
    cin >> ooo;
    if(ooo == 'g')
    mood.addpos(5);
    else
    mood.addneg(5);
}while(true);
    mood.stot();
