C++ If Else - APAMBAPAM

C++ If-Else Statement

The if-else statement in C++ allows you to execute one block of code if a condition is true and another block if the condition is false. It is an extension of the basic if statement for handling two possible outcomes.

Syntax

if (condition) {
    // Code to execute if condition is true
} else {
    // Code to execute if condition is false
}

Example Program

#include <iostream>
using namespace std;

int main() {

    int number;
    cout << "Enter a number: ";
    cin >> number;

    // If-Else statement
    if (number % 2 == 0) {
        cout << "The number is even." << endl;
    } else {
        cout << "The number is odd." << endl;
    }

    return 0;
}

Output (example)

Enter a number: 7
The number is odd.

Key Points

The else block executes only if the if condition is false.
You can have multiple if-else if-else chains to check multiple conditions.
Braces { } are optional for single statements but recommended for clarity.
