int main()

{

srand(0);

// Grading Note : Comment each task with the given description

// Task 1. Create a pointer to an int and set to to nullptr

// Task 2. Create a Dynamic array of 100 ints and assign the pointer in Task 1

// Task 3. Using a for loop - Load all 100 elements with values from the takeANumber() method

// Task 4. Using a for loop - Display all items in the array

// Task 5. Delete the dynamically created array

// Task 6. Repeat the above steps 1 - 4 but use Smart Pointers described in section 9.10
