stl stack pop

**Prototype:**

**原型：**

stack<T> st; //declaration
        st.pop();

**Parameter:**

**参数：**

No parameter passed

**Return type:** void

**返回类型：** void

**Header file to be included:**

**包含的头文件：**

#include <iostream>
        #include <stack>
        OR
        #include <bits/stdc++.h>

**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
