What is the if-else statement in C++?

Can you explain the if-else statement in C++?

Sure! The if-else statement allows you to execute different code based on a condition. If the condition is true, the code inside the 'if' block runs; otherwise, the code in the 'else' block runs.

Can you give me a simple example?

Of course! Here's a basic example:

int number = 10;
if (number > 0) {
    cout << "Positive number";
} else {
    cout << "Non-positive number";
}

What happens if I have multiple conditions?

You can use 'else if' to check multiple conditions. For example:

if (number > 0) {
    cout << "Positive";
} else if (number < 0) {
    cout << "Negative";
} else {
    cout << "Zero";
}

Are there any common mistakes to avoid?

Yes! A common mistake is forgetting to use curly braces for multiple statements. Always use braces to avoid logical errors.
