Stack Adaptor in C++

This C++ program illustrates usage of a adaptor called stack. An adapter is a data type that adapts a container to provide specific interface. Stack provides facility to push elements into it and pop them.

Here is the source code of the C++ program illustrates usage of stack. The C++ program is successfully compiled and run on a Linux system. The program output is also shown below.

$ ./a.out
Top element of stack 'f'
Top element of stack 'e'
Top element of stack 'd'
Top element of stack 'c'
Top element of stack 'b'
Top element of stack 'a'
Stack is empty!
