Instructions You are provided with a main function, and the start of the NumberList class. This class will st of integers, and then provides a getNumber function to return the value at any index in this array, and a setNumber to set one. Your task is to fill in a non-default constructor and a destructor for the class. ore a dynamically allocated array NumberList -array: int* -size: int +NumberList(size) +NumberList() +getNumber(index) : int +setNumber(index, value): void +displayList): void 1. Copy the provided code: mkdir check13a cd check13a cp /home/cs165new/check13a/* . 2. Implement a non-default constructor that accepts an integer for the size of the number list. It should: 1. Dynamically allocate an array of that size 2. Save the size in the member variable named, "size". 3. Fill in a default value of 0 for each spot in the array 3. Implement a destructor that frees up the memory of the array. It should 1. Delete the dynamically allocated array 2. Set the array pointer to be NULL. 3. Output a message that says, "Freeing memory". Note that we normally wouldn't output a message like this in a destructor, but this informs the testbed that you are using your destructor. 4. A main function is provided for you that will create and use some NumberList objects. You should not change this function. All vou need to do is add the constructor and destructor mentioned above
