Chapter 9.3, Problem 9.12CP

Explanation of Solution

Method overloading:

• • Method overloading means that a class contains multiple methods with the same name, but different types of parameters.
• • It is one of the features of polymorphism in object oriented programming.
• • When differentiating overloaded method, the compiler does not consider the return type.
• • When two methods are declared with the same signature and different return types, then it throws a compile-time error.
• • Method overloading takes place by changing:
  • ○ Number of parameters in two methods.
  • ○ Order of parameters of methods.
  • ○ Data types of parameters of methods.

Example:

//Include libraries

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text.RegularExpressions;

//Define namespace

namespace ParameterizedConstructorExample

{

  //Define a class

  class Sample

  {

            // Method to add two integer values

            public int Add(int a, int b)

            {

                //Assign value

                int sum = a + b;

                //Display value

                return sum;

            }

            //Method to add three integer values

            public int Add(int a, int b, int c)

            {

                //Assign value

                int sum = a + b + c;

  //Display value

                return sum;

            }

            // Main Method
