Please answer in C language.

Implement the functions growArray and addStudent as prototyped. If addStudent is called and the array is full, use growArray to increase the array's capacity before adding the student. Hint: The array in StudentArray is a pointer to a dynamically allocated block of memory. Is there any reason we can't point it to a larger, newly allocated block?
