    A little problem here

    I am havi9ng some problem with some code. I am making up a text map for my game I have planned, and want to output it onto the screen.

    Code:
    #include <iostream.h>
    #include <stdio.h>
    #define PLAYER 3
    int i, j;
    int main()
    {
    
    	int grid[20][20] = { 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,
    		                 1,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,1,
    						 1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,
    						 1,1,0,0,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,
    						 1,1,0,0,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,
    						 1,1,0,0,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,
    						 1,1,0,0,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,
    						 1,1,0,0,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,
    						 1,1,0,0,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,
    						 1,1,0,0,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,
    						 1,1,0,0,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,
    						 1,1,0,0,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,
    						 1,1,0,0,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,
    						 1,1,0,0,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,
    						 1,1,0,0,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,
    						 1,1,0,0,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,
    						 1,1,0,0,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,
    						 1,1,0,0,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,
    						 1,1,0,0,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,
    						 1,1,0,0,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0};
    
    
    
    grid[5][5] = PLAYER;
    
    
    for (i = 0; i < grid;i++)
    {
    	for (j = 0; j < grid; j++)
    	{
    	cout << grid[i][j];
    	}
    }
    
    
    		return 0;
    }
    here are the errors:
    Code:
    :\Program Files\DevStudio\MyProjects1\Game\Main.cpp(36) : error C2446: '<' : no conversion from 'int (*)[20]' to 'int'
                                                                            This conversion requires a reinterpret_cast, a C-style cast or function-style cast
    C:\Program Files\DevStudio\MyProjects1\Game\Main.cpp(38) : error C2446: '<' : no conversion from 'int (*)[20]' to 'int'
                                                                            This conversion requires a reinterpret_cast, a C-style cast or function-style cast
    thanks in advance

    btw, if I just use a single cout call, I get a hexdecimal code.

    you could do this, other people know more than i do, so maybe there is another way.

    Code:
    for (i = 0; i < 20;i++)
        {
            for (j = 0; j < 20; j++)

    	grid[5][5] = PLAYER;
    
    
    	for (int i = 0; i < GRID_SIZE; i++)
    	{
    		for (int j = 0; j < GRID_SIZE; j++)
    		{
    			std::cout << grid[i][j];
    		}
    		std::cout << '\n';
    	}
    	return 0;
    }

    thanks, that worked, I guess it was just some bizzare MSVC thing.

    you can't do
    Code:
    for(i = 0; i < grid; i++)
    because, I think (at least it makes sense to me), it doesn't know which size, if its rows or columns. you need to specify if it is rows or columns for grid.
