# If-else Statement in C++

**if-else statement**

`if`

statement is most commonly used with the following format:

if(expression) { statement 1 } else { statement 2 }

where `else`

part is optional.

In this case, either of the two statements are executed depending upon the value of the **expression**. If the **expression** has a non-zero value (i.e., if the **expression** is true), then **statement1** will be executed. Otherwise (i.e., if **expression** is false), **statement2** will be executed.

**Example:**

Given here is a program which reads a number and then prints whether the given number is even or odd.

Note: If we divide a number by 2 and if the remainder is 0 then the number is EVEN else the number is ODD

#include<iostream.h> void main() { int n; cout << "Enter a number :"; cin >> n; if(n%2 == 0) cout << "The number is EVEN"; else cout << "The number is ODD"; }
