I'm so close! Minesweeper
There's just this tiny logical error in my code somewhere.
There's mulitple print outs that won't appear in the final program, but I'm using them to figure out were I went wrong. How do I get the B's to change to X's?
Code:
#include <iostream>
#include <iomanip>
#include <conio>

void fill_array_with_bombs(char minefield[10][10], int r1, int c1);
