game programing

[moot1]

hello. do i need to learn anything else before i get into graphics and game programming.here is a program that i use everything i know

#include <iostream>
#include <cstdlib>

using namespace std;

int main()
{
    system("TITLE calculator");
    system("COLOR 02");

	int Total = 0;
	int Amount;
	int Number;
	int whatoperation;
	int answertoaverage;
	int restart;

	loop:
    system("CLS");

	cout << "Here are your choices(enter the number before the operation)" << endl << endl;
	cout << "1.Addition" << endl;
	cout << "2.Subtraction" << endl;
	cout << "3.Multiplication" << endl;
	cout << "4.Division" << endl;
	cout << "5.Average Calculator" << endl;

	cin >> whatoperation;

	system("CLS");

	switch(whatoperation){
    case 1:
    cout << "Enter in how many numbers you want to use" << endl;
	cin >> Amount;

	for(int i = 0; i < Amount; i++)   // Keeps looping until i == Amount
	{
		cout << "Number " << i << ": " ;  // Shows user what number they are entering
		cin >> Number;

		Total = Number + Total;  // Adds number to total
	}

	cout << "The total is " << Total << endl;  // Prints out total value when loop has finished
	break;

	case 2:
	cout << "Enter in how many numbers you want to use" << endl;
	cin >> Amount;

	for(int i = 0; i < Amount; i++)
	{
		cout << "Number " << i << ": " ;
		cin >> Number;

		if(i == 0)
		{
			Total = Total + Number;
		}

		else
		{
			Total = Total - Number;
		}
	}

	cout << "The total is " << Total << endl;
	break;

	case 3:
	cout << "Enter in how many numbers you want to use" << endl;
	cin >> Amount;

	for(int i = 0; i < Amount; i++)
	{
		cout << "Number " << i << ": " ;
		cin >> Number;

		if(i == 0)
		{
			Total = Total + Number;
		}

		else
		{
			Total = Total * Number;
		}
	}
	cout << "The total is " << Total << endl;
	break;

	case 4:
	cout << "Enter in how many numbers you want to use" << endl;
	cin >> Amount;

	for(int i = 0; i < Amount; i++)
	{
		cout << "Number " << i << ": " ;
		cin >> Number;

		if(i == 0)
		{
			Total = Total + Number;
		}

		else
		{
			Total = Total / Number;
		}
		cout << "The total is " << Total << endl;
	}
	break;
	case 5:
	cout << "Enter how many numbers you want to find the average of: ";
	cin >> Amount;

	for(int i = 0; i < Amount; i++)
	{
	    cout << "Number " << i << ": " ;
		cin >> Number;

		Total = Number + Total;
	}
	answertoaverage = Total / Amount;
	cout << "The average of those " << Amount << " numbers is " << answertoaverage << endl;
}
	cout << "enter 1 to restart or 2 to quit: ";
	cin >> restart;
	if(restart == 1){
	    goto loop;
	    }

    system("pause");
	return 0;
}

try to read and create all practical tasks on http://en.wikipedia.org/wiki/The_C_Programming_Language
and http://en.wikipedia.org/wiki/The_C%2B%2B_Programming_Language books

learn bool very helpful

learn bool very helpful

is that all i need to learn and is win32 GUI a good way to make games?

First, you'll want to learn how to write your own functions and classes. You can theoretically make an entire game in just the main function, but it would be almost impossible to read and might take a long time to compile.

Also learn to use pointers (and references, which are very similar). Practice using the operator new, and learn how to avoid memory leaks by using delete.

Keep studying classes until you understand how to apply polymorphism. From there, you should get a good idea of how to structure your program.

At that point, you should throw out the windows API and get SDL. It allows you to create a window and draw on it in 2d, and also takes care of keyboard and mouse input, sound, and some image loading. You can also create 3d games with it by binding the window to Direct3d or preferably OpenGL. Best of all, you will easily be able to port your game to Mac and Linux machines.

Also, never use system() in code that other people will run. It's a virus waiting to happen.
