C ++ STL stack and stlstack

Because vector is used, we forget to have a stack. Today we only need to think about the value at the top of the stack. stack is very convenient and easy to use. Let's look at the following example:

1 # include <stack> 2 # include <iostream> 3 using namesapce std; 4 5 int main (void) 6 {7 stack <int> v; 8 v. push (0); 9 v. push (1); 10 cout <v. size () <endl; 11 cout <v. top () <endl; 12 cout <v. empty () <endl; 13 v. pop (); 14 cout <v. top () <endl; 15 16}
