Write a program in Java to Swap two digits using a third variable. import java.util.Scanner; class Swapping { public static void main(String args[]) { int first_no, sec_no, third_no; System.out.println(“Enter first_no and sec_no”); Scanner in = new Scanner(System.in); first_no = in.nextInt(); sec_no = in.nextInt(); System.out.println(“Before Swapping\nfirst_no = “+first_no+”\nsec_no = “+sec_no); third_no = first_no; first_no = … Read more
In this tutorial, I am going to show you how to take input from users in Java using two different ways. You can follow any method(Scanner, Buffered) according to your convenience. To understand how we get input from users in Java we first must know the following two things : System.out – Java uses System.out … Read more
Visibility modes in C++ Visibility modes in C++ refer to the accessibility of class members (such as variables and functions) from different parts of a program. C++ provides three visibility modes: public, private, and protected. These modes control the access levels of class members concerning the outside world and derived classes.

In C++, the “this” pointer is a keyword that represents a pointer to the instance of the class to which the member function belongs. It is implicitly passed as a hidden argument to all member function calls. Here’s a basic explanation of the “this” pointer: Types of this pointer Pointer to the Current Object: Inside … Read more
In C++, enumeration (enum) is a user-defined data type that consists of named integral constants. Enums are useful for creating more readable and self-explanatory code by assigning names to numeric values. Here’s a basic example of how to use enums in C++: #include <iostream.h> // Define an enumeration named Color enum Color { RED, … Read more
