#include <iostream> 
#include <stack> 
using namespace std; 
  
int main() 
{ 
    // Empty stack 
    stack<int> mystack; 
    mystack.push(0); 
    mystack.push(1); 
    mystack.push(2); 
  
    // Printing content of stack 
    while (!mystack.empty()) { 
        cout << ' ' << mystack.top(); 
        mystack.pop(); 
    } 
}

get last element of stack c++

// stack::top
#include <iostream>       // std::cout
#include <stack>          // std::stack

int main ()
{
  std::stack<int> mystack;

  mystack.push(10);
  mystack.push(20);
  // .top() gets the last/top element of stack c++
  mystack.top() -= 5;

  std::cout << "mystack.top() is now " << mystack.top() << 'n';

  return 0;
