c# practical final

Q1)Simple Program with C#

a) Write a console application that obtains four int values from the user and displays the sum of that four values.

using System;using System.Collections.Generic;using System.Linq;using System.Text;

namespace ConsoleApplication3{ class Program { static void Main(string[] args) { int n1, n2,n3,n4, sum; Console.WriteLine("Enter 1st no."); n1 = Convert.ToInt32(Console.ReadLine()); Console.WriteLine("enter 2nd no."); n2 = Convert.ToInt32(Console.ReadLine()); Console.WriteLine("Enter 3rd no."); n3 = Convert.ToInt32(Console.ReadLine()); Console.WriteLine("Enter 4th no."); n4 = Convert.ToInt32(Console.ReadLine()); sum = n1 + n2 + n3 + n4; Console.WriteLine("\n Sum of four int values are {0}", sum); Console.ReadKey();

} }}

Output:

b) If you have two integers find the Leap year


namespace leapyear{ class Program { static void Main(string[] args) { int y, r; Console.WriteLine("enter the year"); y=Convert.ToInt32(Console.ReadLine()); r=y%4; if(r==0) { Console.WriteLine("leap year"); } else { Console.WriteLine("not a leap year"); } Console.ReadKey(); } }}

OUTPUT:-

c) Write a program to print a Reverse no.using System;using System.Collections.Generic;using System.Linq;using System.Text;

namespace reverse{ class Program { static void Main(string[] args) { int rev=0, n, r; Console.WriteLine("Enter the no."); n = Convert.ToInt32(Console.ReadLine()); while (n > 0) { r = n % 10; rev= rev * 10 + r; n = n / 10; } Console.WriteLine("reverse no.is:-{0}", rev); Console.ReadKey(); } }}

Output:

d) Write a console application that places double quotation marks around each word in a string.


namespace ConsoleApplication3{ class Program { static void Main(string[] args) { string str = "India is my country"; string[]words =str.Split(' '); Console.WriteLine("Given string is :{0},str"); Console.WriteLine("The result is :"); foreach(string word in words) { Console.WriteLine("\"{0}\"",word); } Console.ReadKey(); } }}

Output:

g) Write programs using conditional statements and loops:

i. Generate Fibonacci Series


namespace ConsoleApplication4{ class Program { static void Main(string[] args) { int a = 1, b = 1, i, c, n; Console.WriteLine("Enter how much long series u want to enter"); n = Int32.Parse(Console.ReadLine()); for (i = 0; i <= n; i++) { c = a + b; Console.WriteLine(c); a = b; b = c; } Console.ReadLine(); } }}

Output:

ii. Generate various patterns (triangles, diamond and other patterns) with numbers.


namespace ConsoleApplication3{ class Program { static void Main(string[] args) { int i, j, n; Console.WriteLine("Enter number"); n = Int32.Parse(Console.ReadLine()); for (i = 0; i < n; i++) { for (j = 0; j <= i; j++) { Console.Write("*"); } Console.WriteLine("\n"); } Console.ReadLine(); } }}

Output:

iii. Test for prime numbers.


namespace ConsoleApplication5{ class Program { static void Main(string[] args) { int[] a = { 5, 10 }; int b = 5; try { int x = a[2] / (b - a[0]); } catch (ArithmeticException e) { Console.WriteLine("divide by zero"); } catch (IndexOutOfRangeException e) { Console.WriteLine("Array error"); } finally { Console.WriteLine("finally block execute"); } int y = a[1] / a[0]; Console.WriteLine(y); Console.ReadLine(); } }}

Output:

iv.Switch Case


namespace ConsoleApplication8{

public delegate void EventHandler(); class deleg { public static event EventHandler display; static void Main(string[] args) { display += new EventHandler(Red); display += new EventHandler(Green); display += new EventHandler(Blue); display += new EventHandler(Yellow); display.Invoke(); Console.ReadLine(); } static void Red() { Console.WriteLine("Rose is Red"); } static void Green() { Console.WriteLine("Grass is Green"); } static void Blue() { Console.WriteLine("Sky is Blue"); } static void Yellow() { Console.WriteLine("Lemon is Yellow"); }

}}

Output:

vi. Test for vowels.


namespace ConsoleApplication3{ class Program { static void Main(string[] args) { int a ; char c; Console.WriteLine("Enter any alphabet:"); a = Console.Read(); c = Convert.ToChar(a); switch (c) { case 'a': Console.WriteLine("a is vowel"); break; case 'e': Console.WriteLine("e is vowel"); break; case 'i': Console.WriteLine("i is vowel"); break; case 'o': Console.WriteLine("o is vowel"); break; case 'u': Console.WriteLine("u is vowel"); break; default: Console.WriteLine("it is not vowel"); break; } Console.ReadKey(); } }}

Output:

Q2 Object Oriented Program with C#

a)Program Using Classes


namespace ConsoleApplication2{ public class circle { const float pi = 3.14f; float r = 14.7f; public float area() { return (pi * r * r); } public void circ() { Console.Write((2 * pi * r)); } } class Program { static void Main(string[] args) { circle c = new circle(); Console.Write("Area of circle:"); Console.WriteLine(c.area()); Console.Write("Circumference of circle:"); c.circ(); Console.ReadKey(); } }}

Output:

C) Program with different features of C#

Constructor


namespace ConsoleApplication1{ public class construct { int x; public construct(int a, int b) { Console.WriteLine(a + b); } public construct(float a, float b) { Console.WriteLine(a + b); } public construct() { x = 2; Console.WriteLine(x+x); } } class Program { static void Main(string[] args) { construct c1 = new construct(3, 5); construct c2 = new construct(12.5f,13.2f); construct c3 = new construct(); Console.ReadKey(); } }}

Output:

Interface


namespace ConsoleApplication2{ interface shape { void calculate(float f1, float f2); } class circle : shape { public void calculate(float x, float y) { Console.WriteLine("Circle area:{0}", 3.14f * x * x); } } class rectangle : shape { public void calculate(float x, float y) { Console.WriteLine("rectangle area:{0}",x*y); } } class Program { static void Main(string[] args) { circle c = new circle(); rectangle r = new rectangle(); shape s; s = c; s.calculate(10, 0); s = r; s.calculate(10, 10); Console.ReadKey(); }

}}

Output:

Function overloading


namespace ConsoleApplication3{ class Program { static void sum(int a, int b) { Console.WriteLine(a + b); } static void sum(float a, float b) { Console.WriteLine(a + b); } static void sum(int a) { Console.WriteLine(a + a); } static void Main(string[] args) { sum(2,3); sum(12.3f, 2.4f); sum(4); Console.ReadKey(); } }}

Output:
