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 $.

#include <iostream> using namespace std; int main() { double price = 3000; if (price >= 500) { cout << "Price is above the minimum." << endl; if (price > 2000) { cout << "But needs to be lower than 2000."; } } else { cout << "Price is too low."; } }

Output:

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

Since both conditions at line 9 and 13 are true, the code at line 15 is executed.
