background color!!!

[merhaba]

hi



Well I am new to C++ and I know little about C++ .All that I see
is "a DOS window" Is there any small and simple program that I play with..
for example ,lets first generate a random number and if number =10 let the
background color of our page becomes green..
This way I will get an idea of how C++ works...or any suggestion??
thanks

Graphics is usualy not what you start with when it comes to C++ because C++ it self doesn't contain any GUI libs. You have to use external libs or API calls or what ever, and then you should know a bit about C++ first. Try to make some hello world apps, read up on about random numbers, and make more functions, then some classes, and stuff. Read the tutorials CornedBee have been so nice to write for us. And if you like it, then buy a book.

It depends on what graphics interface you want to use. If you want to change the background color of a console window, then you have to color each line and it can get messy. I don't believe that would even color the entire window.

Do you want to make an empty window with a color in it that changes? Do you want to change the background of a console program? Do you want to change the background color of a program you're working on? if so, what GUI are you using?

We need more information to help you out but I agree with the suggestion already made. If you don't know much of C++, do the non-GUI stuff first and buy a book. Reading the tutorials here is also a good start.

GUI "Graphics User Interface"

Definitly is not the best place for you to start you new found task of tutoring yourself through C++.

I would start with like suggested a hello app like, this one is a bit beefed up, I just wrote it now and tested it...so it should work.
#include <iostream.h>

int main()
{
    bool bRunning = true;
    int Choice = 0;

    while (bRunning)
    {
        cout << "*******************" << endl;
        cout << "*Choice 1: (Hello)*" << endl;
        cout << "*Choice 2: (Exit) *" << endl;
        cout << "*******************" << endl << endl;

        cout << "Enter your choice: ";
        cin >> Choice;
        cout << endl << endl;

        if (Choice <= 0 || Choice > 2) cout << "Invalid Selection!" << endl;
        else if (Choice == 1) cout << "HELLO WORLD COMPLEX!!!!" << endl << endl << endl;
        else if (Choice == 2) bRunning = false;
    }

        cout << "Good-Bye!" << endl;

        return 0;
} 

Understand that, and then continue.

Familiarize yourself with the Set/GetConsoleTextAttribute for colour changes in the console.

The others are right though; familiarize yourself with the language, itself, before anything fancy.

Remember, in the C++ standard, the .h is gone and it should be just <iostream>. <iostream.h> will still work but isn't standard. Also, including <iostream> guarentees all functions, types, ect in iostream will be included but may not come from just iostream.h. Where as iostream.h may or may not include all functions, types, ect that iostream should have.

I'm not sure how well I explained that one. Maybe I can find a decent article about it.
