C Sharp For Loop

C# For Loop

To iterate a specified code for multiple times, the C# for loop is used. It is recommended to use the For loop when the number of iterations is fixed. The syntax and behavior of C# for loop are the same as that in C or C++; the variable is firstly initialized, the conditions are then checked and finally, the value of the variable is increased or decreased.

Syntax:

for (initialization; condition; increase/decrease)
{  
//code to be executed  
}  

Example:

using System;  
public class Example  
    {  
      public static void Main(string[] args)  
      {  
          for(char x='a'; x<='p'; x++)
		  {    
            Console.WriteLine(x);    
          }    
      }  
    }

Output:

Explanation:

In the above example, we are using a simple program to display the use of the For loop in C#.

C# Nested For Loop:

When a For loop is used inside another For loop, then it is called nested For loop in C#. The outer loop of a nested For loop is executed only one time when the inner loop of the nested For loop is completely executed, i.e, if the outer loop is executed 3 times and the inner loop is executed 5 times, then the inner loop will be executed 5 times for each outer loop i.e. total 15 times.

Example:

using System;  
public class Example  
    {  
      public static void Main(string[] args)  
      {  
          for(char x='a'; x<='d'; x++)
		  {    
            for(int y=1; y<=4; y++){    
                    Console.WriteLine(x+ " "+ y);    
                }     
          }    
      }  
    }

Output:

Explanation:

In the above example, we are using a simple program to display the use of the Nested for loop in C#.

C# Infinite For Loop:

To execute a For loop for the infinite times, the double semicolon is used in for loop, and such a loop is called Infinite For loop in C#.

Example:

using System;  
public class Example  
    {  
      public static void Main(string[] args)  
      {  
          for (; ;) 
		  {       
                    Console.WriteLine("Stop Me if you can!!");       
          }    
      }  
    }

Output:

Explanation:

In the above example, we are using a simple program to display the use of infinite for loop in C#.
