Using the stack class, write a function called loadstack() that returns a stack that is already loaded with letters of the alphabet (a-z.). Assign this stack to another object in the calling routine and prove that it contains the alphabet. Be sure to change the stack size so it is large enough to hold the alphabet.

// Declare a stack class for characters.
class stack {
