C++ examples for STL:vector

Description

Insert element to vector at the end

Demo Code

#include <iostream>
#include <vector>
using namespace std;
void show(const char *msg, vector<char> vect);
int main() {//from   w w w . ja v  a  2s  . c o  m
   // 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";
   // Create another vector.
   vector<char> v3;
   v3.insert(v3.end(), 'X');
   v3.insert(v3.end(), 'Y');
   v3.insert(v3.end(), 'Z');
   show("The contents of v3: ", v3);
   cout << "\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";
}
