C# Empty Statement(;)

Empty statement is used when you no need to perform an operation where a statement is required. It simple transfers control to the end point of the statement. It is also very useful with while loop with blank body and label statements.

Example:

using System;

namespace empty_statement
{
  class Program
   {
   public bool print()
   {
   Console.WriteLine("Aav Kumar ");
   return true;
   }
     static void Main(string[] args)
   {
   int i = 0;
   Program p = new Program();
   while (p.print())
   {
     ; //Empty Statement
   }
   Console.WriteLine("i = {0}", i);
   Console.ReadLine();
   }
   }
}

Note: It processes infinite loop so terminating the program press ctrl+c.

Output

Aav Kumar
Aav Kumar
Aav Kumar
Aav Kumar
Aav Kumar
Aav Kumar
Aav Kumar
Aav Kumar
Aav Kumar
Aav Kumar
Aav Kumar
Aav Kumar
Aav Kumar
Aav Kumar

using System; class sevenday { public static void Main() { int num1; Console.WriteLine("Enter Number From 1 - 7 to find the correponding day"); num1=Convert.ToInt32(Console.ReadLine()); switch(num1) { case 1: Console.WriteLine(" 1 is Monday"); break; case 2: Console.WriteLine("2 is tuesday"); break; case 3: Console.WriteLine("3 is wednesday"); break; case 4: Console.WriteLine("4 is Thrusday"); break; case 5: Console.WriteLine("5 is friday"); break; case 6: Console.WriteLine("6 is saturday"); break; case 7: Console.WriteLine("7 is sunday"); break; default: Console.WriteLine(" Your Number is Invalid Please Enter Correct Number"); break; } } }

Swaping two number using third variable by making object

using System; class Mark { int a,b,temp; \\ taking three variable. public void Swapnum() \\ here i take input on this function { Console.WriteLine("Enter your 1st number"); a=Convert.ToInt32(Console.ReadLine()); Console.WriteLine("Enter your 2st number"); b=Convert.ToInt32(Console.ReadLine()); } public void Swapsum() { temp=a; \\ stroing value of 'a' on temp a=b; \\stroing value of 'b' on 'a' b=temp; \\stroing value of 'temp' on 'b' } public void Display() { Console.WriteLine("your swap number is --: {0}",a); Console.WriteLine("your swap number is --: {0}",b); } public static void Main() { Mark av=new Mark(); av.Swapnum(); av.Swapsum(); av.Display(); } }

C# Function Examples

Example: Write a program to explain method in C#. Create a static function add() that accept two number from user and returns sum of the number. using System; namespace Example1 { class calculation { static int num1, num2, result; public static void add() { Console .Write( "Enter number 1st.\t" ); num1 = Convert .ToInt32( Console .ReadLine()); Console .Write( "Enter number 2nd.\t" ); num2 = Convert .ToInt32( Console .ReadLine()); result = num1 + num2; Console .Write( "\nAdd = {0}" , result); Console .ReadLine(); } } class Program { s...
