Text file parsing

how in C++ would you go about parsing text files.

It depends on the format of the text file. What do you want to do? Read something like a .ini file (pairs of identifiers/values), make a scripting langauge? Read straight data?

My guess is that in C you would use pointers or indexes into arrays, while in C++ you would use iterators and generic containers.

What is parsing?
(no I don't know what parsing means, shoot me)

!bang!

What I need to do is parse a text file for commands.



example:


MakeWin("Window Title Goes Here", left, top, 100,100)

and I need these commands to run in my main program.

I have these functions in my program I just need to get the commands from the file to implement them.

void MakeWin(char *WindowTitle, int x, int y, int xx, int yy);


is how I declared the function and then I have a library that has that function within it, that I have written.

I am making a multitasking gui app for dos that I uses my own custom commands for both drawing and getting mouse clicks, etc.

The only way I have found to multitask is to execute scripts rather than .exe files.

Code:

---

[File.txt]
Window Title ;self explanitory
100 ;x
100 ;y
100 ;width
100 ;height

---

Code:

---

[Part of File.cpp]
char WindowTitle[100];
char x[4], y[4], width[4], height[4];
int ix, iy, iwidth, iheight;
ifstream fileload("File.txt");

fileload.getline(WindowTitle, 100, ';');
fileload.getline(x, 4, ';');
fileload.getline(y, 4, ';');
fileload.getline(width, 4, ';');

ix = atoi(x);
iy = atoi(y);
iwidth = atoi(width);
iheight = atoi(height);

MakeWin(WindowTitle, ix, iy, iwidth, iheight);

I dont know if you can get ints with getline() so i just stored them in a char then atoi'd them :)

Thanks much okismokie, um

is there a way to keep the command and the variables on the same line like the cpp compilers do.
