Course Introduction:The return value type of a C++ function defines the operation result after the function is executed. Basic types include void (returns no value), bool (true or false), and numerical types (integer and floating point). Pointer types point to objects or dynamically allocated memory. Reference types provide direct access to original variables. Practical case: The maximum value calculation function returns the maximum value of two integers, and the dynamic memory allocation function returns a pointer to the allocated space.
