Usage:

用法：

The function pops the top element from the stack.

该函数从堆栈中弹出顶部元素。

Time complexity: O(1)

时间复杂度：O(1)

Example:

例：

    For a stack of integer,
    stack<int> st;
    st.push(4);
    st.push(5);
    stack content:
    5 
C++ implementation:
Output
...use of pop function...
stack elements are:
top element is:6
top element is:5
top element is:4
stack empty
3 pop operation performed total to make stack empty
