C++ Shoft Hand If Else

C++ offers a compact way to write if...else statements using the ternary operator (? :). This operator condenses decision-making logic into a single line, making code more readable and efficient.

How the Ternary Operator Works

Instead of writing a full if...else statement, the ternary operator allows for a quick evaluation of a condition.

Syntax

variable = (condition) ? expressionTrue : expressionFalse;

• If the condition is true, the expressionTrue is executed.
• If false, the expressionFalse runs instead.

Example: Traditional if...else Statement

#include <iostream>
using namespace std;

int main() {
    int temperature = 30;

    if (temperature < 25) {
        cout << "It's a cool day.";
    } else {
        cout << "It's a warm day.";
    }

    return 0;
}

Example: Using the Ternary Operator

The same logic written more concisely:

#include <iostream>
#include <string>
using namespace std;

int main() {
    int temperature = 30;
    string weatherStatus = (temperature < 25) ? "It's a cool day." : "It's a warm day.";

    cout << weatherStatus;
    return 0;
}
