read them in as characters so that you can read them one character at a time.
is there any other way like to use setprecision to only read in 1 thing?
setprecision() is for setting the decimal output of a stream.
If your grid is just characters, you should just use chars, then:
If you have the file already opened, and your pointer allocated, then just use fstream.read().
read() may not work because it would also read in the '\n' line terminators. I think call get() to read each character one at a time would work, convert the char to int when inserting into the grid
char c;
ifstream in("filename.txt");
in.get(&c);
// or this
in >> c;
grid[i][j] = c-'0'; // convert char to intWe're a friendly, industry-focused community of developers, IT pros, digital marketers, and technology enthusiasts meeting, networking, learning, and sharing knowledge.
