Help with partial match peg counter in Mastermind game C++ code

GroovyJack (40)
Like the title says, I am coding mastermind in C++ have already completed it, the counter pegs are gold for a pure match, and silver for a partial match. I have the gold working correctly but can't get the partial match counter to work for the life of me.

Here is the code so far:

The issue I'm getting are the silver counter not working right, it will count right the first turn, but the second turn will be off. Also the game lets turns go to 6 when they should not go beyond 5 turns, or it should print the losing game message. No matter what the game will not print the losing game message when a value of -1 is returned. The 1 value returned for a winning game works, but only rarely. Please help me figure this out.

Your main should be something like this.

int main ( ) {
   mastermind game({"r","g","r","b"});
   int gold, silver;
   int gameResult = game.move({"g","b","r","r"}, gold, silver);
   cout << "Gold pegs: " << gold << endl;
   cout << "Silver pegs: " << silver << endl;
}

Along with the minimum class implementation to show the problem you're looking at.

Having gone through this exercise, you might just discover the problem anyway because it forces you to really look at just one issue.

What this gives you is
- No cumbersome UI to fiddle with every time you want to test an idea.
- No irrelevant functionality like load and save.
- No guessing what we're supposed to type in.
- No code spread across multiple files and multiple posts in a thread.

It's just a simple single file, single post, code that can be dropped directly into a file, compiled and tested without any additional effort.

The more you make people work to get into a position to help you, the less likely it is to happen.

FWIW, I think you're double-counting.
If you guess "rbbb" against "grbr", you only count the "r" once, not twice.
