I know its really simple question, but i cant find answer by myself. I got txt file in this form:

0 0 0 0
1 16 0 1
2 32 0 1
3 48 0 1
b 16 16 0

For now i have:

std::ifstream odczyt2;
odczyt2.open("dodatki/textures.txt");
if (odczyt2.is_open())
{
    for (int y = 0; y < 4; y++)
    {
        for (int x = 0; x < 39; x++)
        {
            odczyt2 >> textury[x][y];
        }
    }
}
odczyt2.close();

And i want to make array of chars, which will look exacly the same.

It is unclear to me what you want. It looks like you are reading in the file so do you have a problem with that or is your issue with displaying the contents? – NathanOliver Feb 08 '16 at 16:03
What you are trying to do is c and there are at least two issues with it: you cannot use `istream::operator>>` to extract to `char *`, and you need to preallocate the memory. The c++ way would be to use a `vector>`... – DarioP Feb 08 '16 at 16:09
Is the last line of data correct? It doesn't fit the pattern of the other lines. – Thomas Matthews Feb 08 '16 at 16:10
*which will look exacly the same* --- the same as what? – n. 1.8e9-where's-my-share m. Feb 08 '16 at 16:13
