C++ if/else

🤔 C++ if/else Statement – Making Decisions in Code

The if/else statement in C++ helps your program make decisions. It checks conditions and runs code based on whether the result is true or false. Think of it as your program saying, “If this happens, I’ll do that!” 🎯

🧠 Syntax of if / else

if (condition) {
    // Code if condition is true
} else if (another_condition) {
    // Code if another condition is true
} else {
    // Code if none of the above conditions are true
}

🔧 Example: Simple if / else

#include <iostream>
using namespace std;

int main() {
    int age;

    cout << "Enter your age: ";
    cin >> age;

    if (age >= 18) {
        cout << "You're an adult!" << endl;
    } else {
        cout << "You're a minor." << endl;
    }

    return 0;
}

🧪 Example: if…else if…else

#include <iostream>
using namespace std;

int main() {
    int score;

    cout << "Enter your score: ";
    cin >> score;

    if (score >= 90) {
        cout << "Grade A!" << endl;
    } else if (score >= 75) {
        cout << "Grade B!" << endl;
    } else if (score >= 60) {
        cout << "Grade C!" << endl;
    } else {
        cout << "Better luck next time!" << endl;
    }

    return 0;
}

💡 When to Use if / else?

• When your program needs to decide between multiple outcomes.
• When different actions must occur based on input or conditions.
• When logic requires branching into different paths.

Now your program can finally think for itself! 🧠💻
