SUMMARY
In C++, methods within a class that perform printing operations to a file or screen utilize the return type 'void'. This keyword explicitly informs the compiler that the method will not return any value upon completion. The use of 'void' is crucial for defining the behavior of such methods, ensuring clarity in code functionality and preventing unintended return value errors.
