First Step

Object-Oriented Programming (OOP) is a technique of computer programming model that organizes software design around data, or objects, rather than functions and logic. We can define an object that as a data field which has unique attributes and behaviour.

Second Step

• Try to know What Is Object-Oriented Programming concepts?
• To better known OOP’s concept try to relate with the real world problems and how real-world problems can be solved by OOP’s.
• Why study of Object-Oriented Programming is necessary and important to learn?
• Know the limitations and advantages of OOP.

Third Step

Now understand above steps try to focus on Structure of Object-Oriented Programming Language as below:-

• What is the definition of Class.
• What is definition Object.
• Know the difference between Class and Object.
• How to use of Classes and Object in program.
• Try to know real-world scenario of class and object.
• Understand all Access Modifiers (public, private, protected, etc.) in OOP’s.

Fourth Step

Important Keywords in OOPs to learn and understand:

• Final Keyword
• Explicit keyword
• This Keyword
• new Keyword
• const keyword
• super keyword etc…

Example:-

#include <iostream>

#include <string>

using namespace std;

class MyExample

{       

public:            

int numdata;       

string stringdata; 

};

int main()

{

MyExample myObj; 

myObj.stringdata = “Your value is…”;

myObj.numdata = 108;

cout << myObj.stringdata;

cout << myObj.numdata << “\n”;

return 0;

}
