hello,

i'm currently learning composition in c++. I created two classes which are tele and person, tele is a short name for telephone :P

tele class can store a person number.

	int Tnumber;
	public:
	tele(int n);
	void printNumber();
};

#endif

:Tnumber(n){}

void tele::printNumber()
{
	cout << Tnumber << endl;

a.printinfo();

	return 0;
}

Shortening class names is a horrible idea, don't do it.
Also, class names start with an uppercase letter unless you're following the boost style (which you aren't) or a similar one.

could you please tell me what is the problem?

Maybe you should start with posting the errors?

cout << " and his telephone is: " << t.printNumber();

t.printNumber() is a function that returns void - it returns nothing. You're trying to output a void object; how can you output something that doesn't exist?

thanks Athar and Moschops

Moschops you are right! that was my error.
Athar thanks for addition information about naming a class.
