15.A(n) error detection code is a digit added to a number (either at the end or at the beginning) that validates the authenticity of the number.
16.When an expression includes a(n) prefix operator, the mathematical operation takes place after the expression is evaluated.
17. The Boolean expression used in an if statement is often a comparison, such as “x greater than y,” but in C++ it can also be a number or a(n) arithmetic expression.
