Answer:
It is true that if a programmer has to create a class clinic with the following data members and functions, they will need to define the data members within the class and create the necessary functions to manipulate and access them. The data members may include patient information such as name, address, and medical history, while the functions could include methods to add new patients, modify patient information, or search for specific patients. The programmer may also need to consider data validation and error handling techniques to ensure the class functions correctly and safely.
