If you want so, you can skip this boring background and head to the question. Quite some time ago I stopped using C++ for a while and started doing some/much programming in C#, using SDL.NET and later my own library ManagedGL. As I got interested in 3D more and more, and the C++ code in the 'MUD Game Programming' book looked really appealing again, I recently partially switched back to C++. But now there's a problem: I never really used the C++ standard library besides some basic cin and cout. Even worse, I was actually coding C+classes, mainly using cstdlib. Using the NeHe tutorials I game quite far, and it looks promising. Now I'm able to draw textured quads and such, I'm going to make a simple maze game - which generally really are 2D besides the graphics, which is nice, because I do know how to make games in general. - question The actual problem: string parsing. Let's say I have this file:

WWWWWWWWWWW
W*........W
WWWWWWW...W
W...@.....W
WWWWWWWWWWW

This is my map. A dot is nothing, a W is a wall, the @ is the start position, and the * is the end position, very simple, so to say. In C#, I'd do it like this:

for(int y=0; y<mapHeight; y++)
	string line = theFileReader.ReadLine();
	for(int x=0; x<mapWidth; x++)
		map[x,y] = createTheTileFromChar(line[x]);

I know how to change this array to a single-dimension array using the y*w+x thingy, but it's really about the string parsing - if you could call it so. How to do this in C++?, using std::string? Then, I'd like to know in what ways these functions are available in C++: TextStream.ReadLine() with std::istream String.Trim() with std::string String.Split() with std::string Thanks!

istream reference -> GetLine() (great reference site for standard C++ functions)

What are those other functions? Browse that website, you might find a similar function.

strtok(), kinda like String.Split().

You'd be better off writing these functions yourself, very fast:

vector<string> Split(std::string str, char del) {    vector<string> strVector;    string temp;    for(int i=0; i<str.length(); i++) {        if(str == del) {            strVector.push_back(temp);            temp = "";            continue; // next loop-round immediately        }        temp += str;    }    return strVector;}

Something like this, not sure if that vector<> part will work, though.

Don't use istream getline like Pipo suggested, it's for char*. Use "std::getline(inputStream, string);"

And for split and trim, see latest version of Boost and it's String Algorithms Library:
http://www.boost.org/doc/html/string_algo.html

Thanks for the info. That'll get me going.

/edit:

How would you implement that map loading thing? Using a filestram or something lik that? Then how to read a single character from it?

Thinking in C++ Volume II

Wow, thanks all! That's very nice. This is more than enough to get me started for sure.
