    minesweeper

    Ok, my wonderful teacher has assigned us to create a minesweeper type game. This is my problem. When a coordinate is inputted, instead of displaying the number of surrounding mines, it will display a heart or club...literally. Que Paso? Also, the random mine generator is not working at all.

    Code:
    #include<iostream>
    #include<iomanip>
    #include<cstdlib>				//includes libraries
    
    using namespace std;
    
    char board[5][8];
    char board2[5][8];
    
    void printMatrix(void)			//precond: none
    {								//postcond: prints a 5 row 8 col board
    	cout<<"  ";
    	cout<<"12345678"<<endl;
    	for(int x=0;x<5;x++){				//prints out board.Blank spaces for 
    		if(x==0)						//"covered" cells, number of bombs 
    			cout<<" +--------+"<<endl;	//surrounding cells that have been 
    		for(int y=0;y<8;y++){			//uncovered, and '?' spots.
    			if(y==0)
    				cout<<" |";
    			if(board[x][y] == '0')
    				cout<<setw(1);
    			else 
    				cout<<board[x][y];
    			if(y==7)
    				cout<<"|";
    			}
    		cout<<endl;
    		
    	}
    	cout<<" +--------+"<<endl;
    }
    
    int checkMatrix(int col,int row)		//precond: receives a cell to check
    {										//postcond: counts the number of mines in 
    	int mineCounter=0;					//surrounding cells and ignores ? and 
    										//cells with nothing in them
    	if(col>7 && row<2){					//calculates mines 4 corners
    		if(board[col-1][row]!= ('0'||'?'))
    			mineCounter++;	
    		if(board[col-1][row-1]!= ('0'||'?'))
    			mineCounter++;

    }
    Any suggestions would be great. Laughing at em would be kinda funny too. Another long nite of C++, or C-- in my case....

    Its printing out a heart or a spade because your checkmatrix returns an int and your board is of type char. So your board is converting the integer into a char and the chars 1-10 are happy faces/card suits etc.

    Change

    return(mineCounter);

    to

    return(mineCounter+'0');
