function's name, with such invoking known as a function call.
◉Type conversion. Answer: A conversion of one data type to
another, such as an integer to a float.
◉Implicit conversion. Answer: When a program automatically

types (as well as others).
◉Type cast. Answer: Converts a value of one type to another type.
