Compare two vector containers. - C++ STL

C++ examples for STL:vector

Description

Compare two vector containers.

Demo Code

#include <iostream>
#include <vector>
using namespace std;
void show(const char *msg, vector<char> vect);
int main() {/*from w w w .  j  a v a 2  s. c om*/
   // Declare an empty vector that can hold char objects.
   vector<char> v;
   // Declare an iterator to a vector<char>.
   vector<char>::iterator itr;
   // Obtain an iterator to the start of v.
   itr = v.begin();
   // Declare a reverse iterator.
   vector<char>::reverse_iterator ritr;
   // Create another vector that is the same as the first.
   vector<char> v2(v);
   show("The contents of v2: ",v2);
   cout << "\n";
   // Compare two containers.
   if(v == v2)
      cout << "v and v2 are equivalent.\n\n";
   return 0;
}
// Display the contents of a vector<char> by using an iterator.
void show(const char *msg, vector<char> vect) {
   vector<char>::iterator itr;
   cout << msg;
   for(itr=vect.begin(); itr != vect.end(); ++itr)
      cout << *itr << " ";
   cout << "\n";
}
