What is the general structure of class in C++?

[sRIPRIYA]

Hello Guys, I want to know what the general structure of class in C++ is. I very much keen to know what it is all about. Is it bit difficult to understand or what? One of my friends was saying that it is very difficult to understand. But, as per my knowledge I don’t think it is difficult. The basic topics are quite easy to understand. I hope that further topics must be also easy. If anybody having any knowledge then please let me know.

A class is a new data type that contains data and function. Collectively these are known as member of the function. Data are known as data member and functions are known as function member. The function defines the set of operation that can be performed on the data members of the class. This property of C++ which allows association of data and function into a single unit is called encapsulation.

    The General Form of class is as follows.

class classname
{
access specifier     Data type variabl_1;
access specifier     Data type variabl_2;
……
access specifier     Data type variabl_n;

access specifier     Return type function_1(argument list);
access specifier     Return type function_2(argument list)
…….
access specifier     Return type function_n(argument list)

};

The class is a reserve keyword.The classname is the name of the class.variable_1 through variable_n are the variables of the class and function_1 through function_n are the functions of the class.The body of the class is enclosed within the curly braces followed by semicolon.

The variable and function of the class has to be declared with one of the access specifier. C++ has three access specifier public ,private , protected.

 For example
class Box
{
   int l,h,w;

public :

void get_data()
{
cout<<”enter the length width and height of box”;
cin>>l>>h>>w;
}

void display()
{
cout<<”the length of box is<<l;
cout<<”the height of box is<<h;
cout<<”the width of box is<<w; 
}
};
