C++ Notes: STL: Example - Vector - reverse input

Vectors (from the Standard Template Library) are an expandable array. Here is the "reverse input" example (see Buffer Overflow) written with a vector. 
// vectors/vector-reverse-input.cpp - Reverses order of input.
// Fred Swartz - 2003-09-30
#include <iostream>
#include <vector>                         // (1)
using namespace std;

int main() {
    //--- Declare a vector.
    vector<int> v;                        // (2)
   
    //--- Read numbers into it.
    int temp;
    while (cin >> temp) {
        v.push_back(temp);                // (3)
    }
   
    //--- Get elements in reverse order.
    for (int i=v.size()-1; i>=0; i--) {   // (4)
        cout << v[i] << endl;             // (5)
    }
   
    return 0;
}//end main
Notes:
  1. The <vector> header must be included.
  2. Declare the vector, enclosing the element type between < and >.
  3. A vector has initial size zero. Add elements to the end by calling push_back() with the value as a parameter. The memory associated with a vector expands as needed.
  4. The current maximum size is obtained by calling size().
  5. Subscription is used to access an element.
