When you first started learning to program in the C/C++ language your programs were mostly unstructured. That is, you put everything in main() and your primary focus was on the basics and the syntax of simple commands for conditional statements and loops. As your knowledge of the language increased you began doing procedural programming. Now you were learning about functions so you added some to the file your main() function was in and called them from main(). With more experience you "graduated" to modular programming in which you added more than one source code file to a project and grouped together similar functions. You may have even begun having those other source files define classes, the beginnings of object oriented programming.
What is an Object?An object is a software "bundle" consisting of a set of variables which define the states the object can exist in and a set of functions that define the behavior of that object. Software objects are often used to model the real-world objects that you find in everyday life.The "objects" used to create an OOP program are classes and structures. A class groups together a number of related fields (member variables) of different data types which define the State of the object, and a number of Methods (functions) which define the Behavior of the object and ways of modifying the object's state.

Object Oriented ThinkingThe main purpose of a computer program is to solve a problem. Using an Object Oriented approach to solving a problem requires a different way of thinking. You must:
What is the value of bundling programs into objects?
What is an object in programming language?In object-oriented programming (OOP), objects are the things you think about first in designing a program and they are also the units of code that are eventually derived from the process.
What is an object in relation to define class in programming language?A Class in object oriented programming is a blueprint or prototype that defines the variables and the methods (functions) common to all Java Objects of a certain kind. An object in OOPS is a specimen of a class. Software objects are often used to model real-world objects you find in everyday life.
What is an object to a class?an object is an element (or instance) of a class; objects have the behaviors of their class. The object is the actual component of programs, while the class specifies how instances are created and how they behave. method: a method is an action which an object is able to perform.
What is the relation between a class and an object?Object is an instance of a class. All data members and member functions of the class can be accessed with the help of objects. When a class is defined, no memory is allocated, but memory is allocated when it is instantiated (i.e. an object is created).
