Nested if & Switch - C++ Crashed

Slide 1 / 15

Nested if — decisions inside decisions

A nested if is simply an if statement placed inside another if statement. It allows you to make a decision, and then based on that result, make another decision.

Think of it like: "If it's raining, and if I have an umbrella, I'll go out."

code_example.cpp

int num1, num2, num3;
cin >> num1 >> num2 >> num3;

// Find the largest of three numbers
if (num1 > num2) {
    // num1 is bigger than num2, now compare with num3
    if (num1 > num3)
        cout << num1 << " is the largest";
    else
        cout << num3 << " is the largest";
} else {
    // num2 is bigger than num1, now compare with num3
    if (num2 > num3)
        cout << num2 << " is the largest";
    else
        cout << num3 << " is the largest";
}
