Class in C++
{tocify} $title={Table of Contents}
Definition of class:-
Class is a user define data type and it binding the data and function in
single unit and give more security by access specifires that can be public private and protected
(We discuss in next blog)
When you define a class, you define a blueprint for a data type. This doesn't actually define any data, but it does define what the class name means, that is, what an object of the class will consist of and what operations can be performed on such an object.
To define a class we using the Class keywords to define the class after that we give class name that can
give by you (because class in a user define data type) to start programming in
this class we use open and close curly braces “{}” in this curly braces we
define access specifier to secure the data by third person after that we
declare the member function. In the end of the close braces we use semicolon to
end the class.
#include <iostream.h> #include <conio.h>
Class simple //Class keyword
and class name
{
Public: // access
specifier
Int x;
Void display() //Class function
{
Cin >>”enter the value of
x”>>x;
Cout<<”value of x is”<<x;
}
};
Void main() //main function
{
simple s1; //creating an object (s1)
s1.display() //call a class function by object
}
