In this tutorial, we are going to see how object slicing in C++. Before diving into the topic let us revise two simple concepts of object oriented programming. Inheritance Polymorphism Inheritance is said to be an IS-A relationship. For e.g. class Animal { // properties common to all animals } class Tiger: public Animal { …
Here you will learn about difference between class and structure. A class and a structure, both are user defined data types and understanding the difference between both of them might be confusing at times. In order to understand this, the following table shows clear differences between the two. Class Structure It is a reference data …
Constructor and Destructor are the special methods which makes our crucial tasks easier while programming. If you have ever worked in programming language like C++ then you must have encountered these two terms. Being methods, they clearly let us implement the reusability of the code. But the talk of the town (esp. for the beginners) …
You may have made program to print numbers from 1 to n using loops, recursion or goto statement. But have you ever thought about doing this without help of loops, recursion or goto? It can be done without using such things as explained in below program.Also Read: C program to find factorial of any number using …
#include<iostream> #include<stdio.h> //used for gets() #include<string.h> //used for strcmp() using namespace std; class String { char str[20]; public: void getdata() //function to read the string { gets(str); } //operator function to overload comparison operator and compare two strings int operator ==(String s) …
In this program we will first create a class demo that contains two float data members a and b. Values of objects d1 and d2 are entered by user and then arithmetic operations are performed on them by overloading binary operators and result is stored in object d3. The code for the program is given …
#include<iostream.h> #include<conio.h> class swap { int a,b; public: void getdata(); void swapv(); void display(); }; void swap::getdata() { cout<<“Enter two numbers:”; cin>>a>>b; } void swap::swapv() { a=a+b; b=a-b; a=a-b; } void swap::display() { cout<<“a=”<<a<<“tb=”<<b; } main() { clrscr(); swap s; s.getdata(); cout<<“nBefore swap:n”; s.display(); s.swapv(); cout<<“nnAfter swap:n”; s.display(); getch(); return 0; }
