push n pop

can someone briefly explain push and pop with a small simpe program writen in c++ here? if possible, ill be thankful! please dont direct me to links etc, i want something on which we can discuss here!! thanks

what's my knowledge about pop / push? all I understood is that pop is used to remove and push is used to add

You are probably talking about a stack. Perhaps googling the subject of "stack" would help?

or push_back / pop_back from std::vector

http://www.cplusplus.com/reference/stl/vector/

Run this code and see if if helps.

Code:

---

#include <iostream>
#include <stack>
 
int main()
{
        std::stack<int> Stack;
 
        for (int i=0; i<10; i++)
        {
                std::cout << "Pushing: " << i << std::endl;
                Stack.push(i);
        }

        while (!Stack.empty())
        {
                std::cout << "Popping: " << Stack.top() << std::endl;
                Stack.pop();
        }
 
        return 0;
}
