بریم چندتا مثال کاربردی از Boolean در C++ ببینیم:

1️⃣ مقداردهی ساده

#include <iostream>
using namespace std;

int main() {
    bool isHungry = true;
    bool isSleeping = false;

    cout << boolalpha;
    cout << "Hungry? " << isHungry << endl;     // true
    cout << "Sleeping? " << isSleeping << endl; // false
}

2️⃣ مقایسه اعداد

#include <iostream>
using namespace std;

int main() {
    int a = 10, b = 20;

    cout << boolalpha;
    cout << (a < b) << endl;   // true
    cout << (a == b) << endl;  // false
    cout << (a != b) << endl;  // true
}

3️⃣ ترکیب منطقی

#include <iostream>
using namespace std;

int main() {
    int age = 19;
    bool hasID = true;

    bool canEnter = (age >= 18 && hasID);

    cout << boolalpha;
    cout << "Can enter? " << canEnter << endl;  // true
}

4️⃣ استفاده در شرط if

#include <iostream>
using namespace std;

int main() {
    bool isRaining = false;

    if (!isRaining) {
        cout << "Go outside!" << endl;
    } else {
        cout << "Take an umbrella!" << endl;
    }
}

5️⃣ استفاده در حلقه while

#include <iostream>
using namespace std;

int main() {
    int count = 0;
    bool keepRunning = true;

    while (keepRunning) {
        cout << "Count = " << count << endl;
        count++;

        if (count >= 3) {
            keepRunning = false;  // متوقف کردن حلقه
        }
    }
}

6️⃣ شرط تو در تو با Boolean

#include <iostream>
using namespace std;

int main() {
    int score = 85;

    if (score >= 90) {
        cout << "Grade: A";
    } else if (score >= 75 && score < 90) {
        cout << "Grade: B";
    } else {
        cout << "Grade: C";
    }
}
