GUI

I was wondering two things:

• What is a good GUI tutorial
• Do you think I'm ready to start using GUI

Code:

#include <iostream>
#include <cmath>

using namespace std;

inline void operations()
{
	cout<<"x,/,+,-,^,s2(square root)\n";
}
float math()
{
	string line;
	float x;
    float y;
    char a;
	float answer;
	int it = 65;
   cout<<"enter an problem (o for operations)";
   getline(cin,line);
   if(line.at(0) == 'o'){
	   operations();
   }
   else{
	   cin>>x>>a>>y;
   }

   
	switch (a){
	case 'o':
		answer = (char) it;
	    operations();
		break;
	case 's':
		answer = sqrt (x);
		break;
	case 'x':
		answer = x*y;
		break;
	case '/':
		answer = x/y;
		break;
	case '+':
		answer = x+y;
		break;
	case '-':
		answer = x-y;
		break;
	case '^':
		answer = pow (x,y);
		break;
	}
	return answer;
}
int main()
{ 
	float answer = math();

	cout<< answer <<"\n";

	system("pause");
}

What operating system are you using?

I'd say you're probably not ready to write GUI code, unless you know what classes are, inheritance, dynamic memory allocation, etc. -- and you've actually used them a little bit. Writing GUIs is hard.

But if you want to try, I can personally recommend Qt as a good GUI library (especially if you're using Linux). Others have also said good things about wxWidgets. Both of these are cross-platform, open source, and C++. One of them might be a good place to start.

thank you and i am usng windows 7

You might want to spend some more time learning C++, get data structures down, those are a big part of GUI.

Start with wxWidgets on windows, and after a while with that, you might try Win32 or MFC.
