c programming   Define a structure called timeOfDay_t with three integer members, hour, minute, and second.  Note: timeOfDay_t should be typedef-ed! Define a function with the following prototype: timeOfDay_t * make_tod(int hour, int minute, int second);  that allocates space on the heap for a new timeOfDay_t structure and returns a pointer to it with the hour, minute, and second set appropriately.

Concept of Pointer Parameter

Pointers are the special variable that stores the variable address, instead of storing the variable value. Pointer is a powerful feature of a programming language. A pointer is mostly used to save memory space and improve execution time.
