Nested if Statements

Nested if Statements

 It is always legal in C# to nest if-else statements, which means you can use one if or else if statement inside another if or else if statement(s).
Syntax The syntax for a nested if statement is as follows:
if( boolean_expression 1)
{
   /* Executes when the boolean expression 1 is true */
   if(boolean_expression 2)
   {
      /* Executes when the boolean expression 2 is true */
   }
}

Example:-

using System; 

namespace DecisionMaking 

{ 

     

    class Program 

    { 

        static void Main(string[] args) 

        {  

            //* local variable definition */ 

            int a = 100; 

            int b = 200;  

            /* check the boolean condition */ 

            if (a == 100) 

            { 

                /* if condition is true then check the following */ 

                if (b == 200) 

                { 

                    /* if condition is true then print the following */ 

                    Console.WriteLine("Value of a is 100 and b is 200"); 

                } 

            } 

            Console.WriteLine("Exact value of a is : {0}", a); 

            Console.WriteLine("Exact value of b is : {0}", b); 

            Console.ReadLine(); 

        } 

    }
