IN C++

Write a program that works with pointers.

• Create 3 pointer variables
  • An integer pointer, a double-pointer, and a string pointer
  • Initialize each to nullptr.
• For each pointer variable:
• Allocate memory by using new. Hint: stringPtr = new string();
• Assign a value by using the indirection operator
• Display the value
• Free the memory

You can either work with each variable one at a time, or you can allocate memory for each, assign a value for each, etc.
