bookTernary Operator

The ternary operator is a powerful tool that often used to make quick decisions in your code and can greatly improve code readability when used appropriately.

condition ? expression_if_true : expression_if_false;

The condition is evaluated. If the condition is true, the expression before the : is executed, otherwise, the expression after the : is executed.

The ternary operator is essentially just an alternative to the if-else statement, providing the code readability and convenience.

int variable;
if (condition)
{
    variable = 25;
}
else
{
    variable = 10;
}

As you can see it using ternary operator can save code space and improve readability and efficiency. However, it is important to save a balance and maintain code maintainability and understandability.

Ternary operators can also be nested to handle more complex conditions. But don't fall into a pitfall full of ternary operatorsю

std::string eligibility = 
    age < 18 
        ? "Too young"
        : (isStudent
            ? (hasJob
                ? "Eligible for student discount"
                : "Eligible for student perks")
            : (hasJob
                ? "Eligible for job-related benefits"
                : "Not eligible"));

It's really hard to understand what is going on. So it is better to limit yourself to a single ternary operator, with a maximum of one level of nesting at any given time.
