Cycle through vector in the reverse direction using a reverse_iterator. - C++ STL

Description

Cycle through vector in the reverse direction using a reverse_iterator.

Demo Code

#include <iostream>
#include <vector>
using namespace std;
void show(const char *msg, vector<int> vect);
int main() {/*w  w  w  .ja  v a2 s  . c om*/
   vector<int> v(10);
   for(unsigned i=0; i < v.size(); ++i)
      v[i] = i*i;
   show("Contents of v: ", v);
   vector<int>::iterator itr;
   vector<int>::reverse_iterator ritr;
   for(ritr = v.rbegin(); ritr != v.rend(); ++ritr)
      cout << *ritr << " ";
   cout << "\n\n";
   return 0;
}
void show(const char *msg, vector<int> vect) {
   cout << msg;
   for(unsigned i=0; i < vect.size(); ++i)
      cout << vect[i] << " ";
   cout << "\n";
}
