    stackst; //declaration
st.push(T item);

Parameter:

参数：

    T item; //T is the data type

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 pushes elements to the stack.

该函数将元素压入堆栈。

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
