You're best bet is to buy a book for C++. You can't just learn from reading though.

I agree,
http://www.cplusplus.com/doc/tutorial/index.html
is very thorough from the start on up.

For a book I recommend "Standard C++ Bible" by Al Stevens and Clayton Walnum. It has a CD-ROM with all the sample code from the book and an integrated compiler, so you can run the code and most importantly experiment with it. That's the way to learn!!!

http://www.cprogramming.com/ also has some helpful tutorials~

I use that site but wen i compile it and try to run it all it does is cmd opens real fast and closes right away...
i tried what they gave me which was this

Quote:

// my first program in C++

#include <iostream.h>

int main ()
{
cout << "Hello World!";
return 0;
}

which doesnt really work.. i get the error which i explained already, but when i try this one

Quote:

#include <iostream>
using namespace std;
int main()
{
cout << "Hello World!" << endl;
cin.get();
return 0;
}

It works cmd opens and i can read hello world.. can someone explain whats hte difference? what exactly does << endl; do?

This would be better..

(Toggle Plain Text)

#include <iostream>
#include <conio.h>
using namespace std;

int main() {
    cout << "Hello world!" << endl;
    // endl = End of line, ends the output line and starts a new one...

    cout << "endl put this here... ";
    cout << "instead of here.";

    getch();
    // included by conio.h
    //   - Waits for keyboard input and the continues...
    //   - Shows nothing on the screen...

    return 0;
}

cool htat works too... what does conio.h do?

Xero · Feb 20th, 2005, 10:26 PM

LOL forget that

just add:
int fsd;
cin >> fsd;

put this at the very end right before return 0;
its cuz some compilers just terminate immediately after execution. Yea, I was quite confused too when I switched compilters from the Borland to Visual Studio .Net (I think). I still don't know why though, but you probably have to add a cin or get char/line or whatever to pause.

Stick with cin.get();. cin >> fsd; uses an unneeded variable, and while getch(); works, it may not work on a different compiler.

oooh i get it!

tempest · Feb 21st, 2005, 11:34 PM

getch() is the best option on a windows compiler. However if you move to linux you have to look to cin alternatives.

As for not working with other (windows) compilers, conio.h was originally developped by borland and as far as i know is currently supported on Microsoft, Borland, and Bloodshed compilers.

conio.h is also evil

(Personal opinion, at least)
