(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 pointer data that held the address of the first element of a dynamic array of integers. initializes the vector to have a size of Write a function called my vector init default) that 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 (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 pointer data that held the address of the first element of a dynamic array of integers. initializes the vector to have a size of Write a function called my vector init default) that zero, capacity of seven and an appropriate value in the data pointer.
