Which of the following can be used as an identifier in both C and C++?
Options
- A. class
- B. return
- C. student_count
- D. More than one of the above
- E. None of the above
Quiz Practice:
C. student_count
Answer: (C) student_count
An identifier is the name given to variables, functions, arrays and other user-defined entities.
student_count is a valid identifier in both C and C++ because it starts with a letter and contains only letters and underscore.
class is a C++ keyword and return is a keyword in both languages, so they cannot be used as normal identifiers.
