Object Oriented Programming

Object Oriented Programming Programming paradigm that represents the concept of "objects" that have data fields (attributes that describe the object) and associated procedures known as methods Programming methodology based on objects, instead of just functions and procedures Focuses on data rather than process As individual objects can be modified without affecting other aspects of the program, it is easier for programmers to structure and organize software programs Easier to update and change programs written in object-oriented languages Simula was the first object oriented programming language Eg: C++, Java, etc. Features of OOPS Objects Referred as instance of class Basic run-time entities in an object-oriented system a person, a place, a bank account, a table of data, etc can be an object They occupy space in memory that keeps its state Each object contains data and code to manipulate the data Classes Blue print or prototype which defi

How structure elements are stored?

The elements of a structure are always stored in contiguous memory locations. This can be illustrated as void main() { struct student { int roll; float marks; char remarks; }; struct student st={200,60.5,'P'}; printf("\nAddress of roll=%u",&st.roll); printf("\nAddress of marks=%u",&st.marks); printf("\nAddress of remarks=%u",&st.remarks); getch(); } Output: Address of roll=65518 Address of marks=65520 Address of remarks=65524 st.roll st.marks st.remarks 200 60.5 ‘P’ 65518 65520 65524

How containership is different than inheritance ?

Inheritance is the mechanism of deriving properties of one class into another. While containership is mechanism in which one class contain objects of other classes as its member. class alpha{_ _ _ _ _ }; class beta{_ _ _ _ _ }; class gamma { alpha a; beta b; _ _ _ _ _ }; All objects of gamma class will contain the objects a and b, this kind of relationship is called containership or nesting.
