1. Write a C++ program that creates a pointer to a double variable. Read in a double into the variable by dereferencing the pointer.
Sample Run:
Enter a number: 5.9

The number entered was 5.9

2. Create a pointer to an array of integers. Use the dereferenced pointer and pointer arithmetic to sum all the numbers in the array and print it.
Sample Run:

Enter an array of size 10
12 -5 9 10 32 -117 258 19 39 6

The sum is 263
