Nested If

Nested if statement is placed inside other if block.

Syntax

if(condition1) { // code to execute if condition1 is true if(condition2) { // code to execute if condition1 is true and condition2 is true } }

Basic example

Let's validate the price of a product in smartphone store and print proper messages about it.

The rule is that price must be above 500 $ and below 2000 $.

using System; namespace csharp { class Program { static void Main(string[] args) { double price = 3000; if (price >= 500) { Console.WriteLine("Price is above the minimum."); if (price > 2000) { Console.WriteLine("But needs to be lower than 2000."); } } else { Console.WriteLine("Price is too low."); } } } }

Output:

Price is above the minimum. But needs to be lower than 2000.

Since both conditions at line 11 and 15 are true, the code at line 17 is executed.
