7. (15 points) In class we created an opaque object for a type called MY_VECTOR that had an internal structure called My_vector consisting of an integer size, an integer capacity, and an integer pointer data that held the address of the first element of a dynamic array of integers. Write a function called my_vector_init_default that initializes the vector to have a size of zero, capacity of seven and an appropriate value in the data pointer. Your function should return the address of an opaque object upon success and NULL otherwise
