Basic C# Console Programs and Concepts

Nemish Lathiya 20se02ce032 Programing With .Net SECE3511 Practical 1 1. Write a C# program to “hello word” in Console application. using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace helloo_word { class Program { static void Main(string[] args) { Console.WriteLine(" Hello Word "); Console.ReadKey(); } } } Nemish Lathiya 20se02ce032 Programing With .Net SECE3511 2. Write a C# program to take user input and print integer value and Name. using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Practical_1._2 { class Program { static void Main(string[] args) { Console.WriteLine("Enter username:"); string userName = Console.ReadLine(); Console.WriteLine("Username is: " + userName); Console.WriteLine("Enter your age:"); int age = Convert.ToInt32(Console.ReadLine()); Console.WriteLine("Your age is: " + age); Console.ReadKey(); } } } Nemish Lathiya 20se02ce032 Programing With .Net SECE3511 3. Create console applications to implement following C# Concepts. Constructor (both) & Destructor using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace BRK.ConstructorExample { class Welcome { // Default constructor public Welcome() { Console.WriteLine("Welcome message from Default Constructor..."); } // Parametarized constructor public Welcome(string name) { Console.WriteLine("\n\nThis message from parametarized constructor"); Console.WriteLine("Welcome to Constructor sample, by {0}", name); } } class Program { static void Main(string[] args) { // Creating object for Welcome class // This will called default constructor Welcome obj = new Welcome(); // Creating object for welcome class by passing parameter // This will called parametarized constructor which matches Welcome pObj = new Welcome("Nemish LAthiya"); Console.Read(); } } } Nemish Lathiya 20se02ce032 Programing With .Net SECE3511 Method Overloading using System; namespace MethodOverload { class Program { // method with one parameter void display(int a) { Console.WriteLine("Arguments: " + a); } // method with two parameters void display(int a, int b) { Console.WriteLine("Arguments: " + a + " and " + b); } static void Main(string[] args) { Program p1 = new Program(); p1.display(10); p1.display(10, 400); Console.ReadLine(); } } } Nemish Lathiya 20se02ce032 Programing With .Net SECE3511 Operator Overloading using System; namespace OperatorOvlApplication { class Box { private double length; private double breadth; private double height; public double getVolume() { return length * breadth * height; } public void setLength(double len) { length = len; } public void setBreadth(double bre) { breadth = bre; } public void setHeight(double hei) { height = hei; } public static Box operator +(Box b, Box c) { Box box = new Box(); box.length = b.length + c.length; box.breadth = b.breadth + c.breadth; box.height = b.height + c.height; return box; } } class Tester { static void Main(string[] args) { Box Box1 = new Box(); Box Box2 = new Box(); Box Box3 = new Box(); double volume = 0.0; Nemish Lathiya 20se02ce032 Box1.setLength(6.0); Box1.setBreadth(7.0); Box1.setHeight(5.0); Box2.setLength(12.0); Box2.setBreadth(13.0); Box2.setHeight(10.0); volume = Box1.getVolume(); Console.WriteLine("Volume of Box1 : {0}", volume); volume = Box2.getVolume(); Console.WriteLine("Volume of Box2 : {0}", volume); Box3 = Box1 + Box2; volume = Box3.getVolume(); Console.WriteLine("Volume of Box3 : {0}", volume); Console.ReadKey(); } } } Programing With .Net SECE3511
