C# | C Sharp for Loop

For loop is used to iterate a part of the code multiple times.  We must use for loop instead of using while and do while if the number of iteration is known in advance. For loop in C# is same as it was In C and C++.

Syntax:
for(<initialization>;<condition>;<increment/decrement>)
{
//Code which is to be executed several number of times
}
C# for loop example:
using System;
public class ForLoopExample1
{
            public static void Main (string[] args)
            {
                        Console.WriteLine("Enter The number of which you want to print the table??");
                        int num=Convert.ToInt32(Console.ReadLine());
                        for(int i=1;i<=10;i++)
                        {
                                    Console.WriteLine(num +"X" +i +"=" +num*i);
                        }
            }          
}
Output
Enter The number of which you want to print the table??
6
6X1=6
6X2=12
6X3=18
6X4=24
6X5=30
6X6=36
6X7=42
6X8=48
6X9=54
6X10=60
C# nested for loop:

Two loops get executed in nested for loop named as inner loop and outer loop. The inner loop iterates n number of times for each outer loop iteration.

Syntax:
for(<initialization>;<condition>;<updation>)
{
            for(<initialization>;<condition>;<updation>)
            {
                        //some statements
                        //the loop iterates until the inner condition fulfills for every outer loop execution             }

C# Nested for loop Example:
using System;
public class Nested_For_Loop_Example2
{
            public static void Main (string[] args)
            {                     
            int row=Convert.ToInt32(Console.ReadLine());
            for(int i=1;i<=row;i++)
            {
                        for(int j=1;j<=i;j++)
                        {
                                    Console.Write("*");
                        }
                        Console.WriteLine();
            }
}
}
Output
Enter The Number of Rows
10

C# Infinite for loop: An infinite loop is the one which iterates infinite number of times. the for loop becomes an infinite loop if the condition provided is never going to be fulfilled.
C# infinite for loop Example: If we put two semicolons only in for loop then the loop will iterate till infinite times. this is the simplest way to create an infinite for loop.
using System;
public class InfiniteForLoopExample
{
            public static void Main (string[] args)
            {
            for(;;)
{
Console.writeLine("this is an infinite loop");
}
}
}
