rationale for your decision.TypedefThe Typedef is frequently used in the C language to declare a synonym for an existing data type. You can also use a preprocessor to do something similar. For example, consider the following example:#define DPS struct S *typedef struct S * tPS;The intent of both of these cases is to define DPS and TPS as a pointer to the struct S. Which method is better? (if any) why?This is a very delicate question, and anyone who answers the question correctly (for the right
