Making decisions

7 min 20 XP + 10 for no hints

if runs code only when a condition is true, and else handles the other case. Conditions use comparison operators like >, >=, == and !=.

Join conditions with && (and) or || (or): if (age >= 13 && age <= 19) is true for teenagers.

The bool type holds true or false, which is a handy way to name a condition: bool isTeen = age >= 13 && age <= 19;

Example (inside main)
int marks = 72;
if (marks >= 40) {
    std::cout << "Pass" << std::endl;
} else {
    std::cout << "Try again" << std::endl;
}
Output
Pass
A single = stores a value. Use == when you want to compare.
