Arithmetic Operations Using An Interface Concept

Introduction to interface

• ”Interface” is the keyword .
• Interfaces define properties and methods, which are the members of the interface.
• Interfaces contains only the declaration of the members in the programming language.

Why use an interface

• Interface is used instead of multiple inheritance.
• Methods are to be declared by the base class and the deriving class implements the functionalities. 

Use of an interface

• It is the responsibility of the deriving class to define the members.
• It provides a standard structure. 

Description

• In this blog, we learn about the interface concept in C# programming language
• To perform arithmetic operations of addition, subtraction ,Multiplication and division, we use interface concept in C# programming language. 

REQUIREMENTS

• Visual Studio 2010.
• Windows operating system Windows 7,8,10.

The code of a program is given below.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace arithmeticinterface {
    public interface interex {
        void add(int a, int b);
        void sub(int a, int b);
        void mul(int a, int b);
        void divi(double a, double b);
        void display();
    }
    class inter1: interex {
        int x, y, z;
        double d;
        public void add(int a, int b) {
            int m, n;
            m = a;
            n = b;
            x = m + n;
        }
        public void sub(int a, int b) {
            int m, n;
            m = a;
            n = b;
            y = a - b;
        }
        public void mul(int a, int b) {
            int m, n;
            m = a;
            n = b;
            z = a * b;
        }
        public void divi(double a, double b) {
            double m, n;
            m = a;
            n = b;
            d = a / b;
        }
        public void display() {
            Console.WriteLine("Addition value is:" + x);
            Console.WriteLine("Subtraction value is:" + y);
            Console.WriteLine("Multiplication value is:" + z);
            Console.WriteLine("Divition value is:" + d);
        }
    }
    class Program {
        static void Main(string[] args) {
            inter1 obj = new inter1();
            int g, h;
            Console.WriteLine("Enter the first Number to perform Arithmetic operations:");
            g = Convert.ToInt16(Console.ReadLine());
            Console.WriteLine("Enter the second Number to perform Arithmetic operations:");
            h = Convert.ToInt16(Console.ReadLine());
            obj.add(g, h);
            obj.sub(g, h);
            obj.mul(g, h);
            obj.divi(g, h);
            obj.display();
            Console.ReadKey();
        }
    }
}

The output is given below.

 

Conclusion

 

I assured that after reading this blog, you all know about an interface in C# programming language.
