STL:<stack> container

For using stack container we have to include <stack> in our program.We already know that stack is last in first out system.Mainly stack has two operations 1.push operation & 2.pop operation.

There are 5 member functions in the <stack> container.They are:

Suppose x is a stack

1.x.push(value);//for inserting a value in stack.

2.x.pop();//for removing the top element.

3.x.top();returns the top element of the stack.

4.x.empty();returns a boolean value that the is empty or not.

5.x.clear();for removing the entire stack.
