C++ STL stack::empty() function with example: In this article, we are going to see how to check whether a stack is empty or not using C++ STL? Submitted by Radib Kar, on February 03, 2019 C++ STL - stack::empty() functionThe function checks whether a stack is empty or not....
size():This function will return the size of the stack container, that is, the total number of elements stored in the stack. The time complexity of this function is O(1). empty():This function will check whether the stack container is empty or not. Similarly, the time complexity for th...
IF (st.empty()) Print "Stack is empty" Else Print "Stack is not empty" Output: Prints "Stack is empty" C ++实现: #include <bits/stdc++.h> using namespace std; int main(){ cout<<"...use of empty function...\n"; int count=0; stack<int> st; //声明栈 st.push(4); //推...
The following example shows the usage of the std::stack::empty() function. At first, we are trying to create a stack s with no elements in it and we verify it using the empty() function. Then, we insert/push element '1' into the stack and use the empty() function to determine ...

Stack是一个后进先出(Last In First Out, LIFO)的数据结构,类似于人们平时堆叠书籍或餐盘的行为。Stack有一些常见的操作,比如push(将元素添加到栈顶)、pop(将栈顶元素移除)和top(获取栈顶元素),以及一个用于判断stack是否为空的函数,即empty。 empty函数是stack容器提供的一种功能,用于检查stack是否为空。当...
The data 4 is pushed in the stack. The data 5 is pushed in the stack. The data 6 is pushed in the stack. The data 7 is pushed in the stack. The data 8 is pushed in the stack. The data 9 is pushed in the stack. stack.IsEmpty() == false Current data is : 9 Current data...
