write a C++ program that will ask the user to enter an integer such as 15, and then assign that integer to a variable of int type named size. Next, create an array of double type whose total number of elements is defined by the size variable, and then assign ptr as pointer that points to the array. Finally, use the typeid() function to display the data type of the ptr pointer.
