Replying to C++: Basic Classes

By the way, the pointer thing is one of the most inportant functionalities in C and C++.

And I also know that allocating memory is also an important factor

Of course, there's the addition of pointers that I have to worry about also.

Although I haven't done extensive programming in C++, I have found that many of the practices in Java are also implemented in C++. Of course, there's the addition of pointers that I have to worry about also.

struct/class difference correctionC++: Basic ClassesA struct is not the "exact same" as a public classFrom C++ standard (11.2.2):"In absence of an access-specifier for a base class, public is assumed when the derived class is declared struct and private is assumed when the class is declared class."Additionally, (11.2):"Member of a class defined with the keyword class are private by default. Members of a class defined with the keywords struct or union are public by default."-reply by richard

Thanks u very much ^^. Your notes are very useful for me. I wish all Learn programming books had clear ideals like yours. You make me to love C++ so more!

Access private member function without using friend class

C++: Basic Classes
I want to use private member function in other class , how can I access without using friend.

-question by Aijaz Ahmad

You can't as that is the idea behind private functions/variables, think of them as globals but only for that class. What you could do(assuming you have access to the source) is create a public "proxy" function think simply passes the given variables to the private function. For private variables I would recommend implanting get/set functions.

example of a get/set

class MyClass
{
	public:
		MyClass() // :) never forget to initialize your values.. bad things will happen if you don't
		{
			number = 0;
		}

		virtual int get_number() // Returns the value of the private member number
		{
			return number;
		} 

		virtual void set_number(int value) // Sets number to equal value
		{
			number = value;
		}

	private:
		int number;
};

Thanks...
Very simple illustrations...!

And Dont forget to end the class with a semi colon ';'

class
{
};

thanks for the tutorial
although i've read it in book
but i more understand read this one
