STL stack queue

#include <iostream>
#include <vector>
#include <stack>
Hi!
In the Standart Template Library I am stading stack and queues.

One way to instantiate is creating a stack that uses an underlying container , in this case vector,

Can anyone give me an example about how to use this?
I mean how can I use the function members of the container vector in the next code?
What is the difference between a simply stack of integers and the stack of integers containes in a vector?

Thanks


using namespace std;

int main()
{

stack<int,vector<int>> mystack; //vector ???????

mystack.push(2);
mystack.push(8);

cout<<mystack.top();

return 0;
}

The second parameter of a stack definition allows you to define which container the stack is supposed to use internally. The default is a deque and you can change it to for example a vector as you suggest.

But this doesn't influence the stack interface, it will remain the same. A stack is a stack. But the properties of the stack will reflect that of the internal container. For example a deque and a vector handles memory differently when they grow/shrink and the stack will adopt the respective behaviour.

I recommend The C++ Standard Library, second edition, by Josuttis as a very good reference for topics like this.

ok thanks... I undertand now :):):):):)
