Explain Applications of Stack ? 

==> Applications of Stack----

• The simplest application of a stack is to reverse a word. You push a given word to stack - letter by letter - and then pop letters from the stack
• Another application is an "undo" mechanism in text editors; this operation is accomplished by keeping all text changes in a stack.
• Evaluation of Expressions
• Language processing::

1. space for parameters and local variables is created internally using a stack.
2. compiler's syntax check for matching braces is implemented by using stack.
3. support for recursion
