Replacing values from a sequence using algorithms replace - C++ STL Algorithm

Description

Replacing values from a sequence using algorithms replace

Demo Code

#include <iostream> 
#include <algorithm> 
#include <vector> 
#include <iterator> // ostream_iterator 
using namespace std; 

int main() //from   w ww . ja v a 2  s.  c  o  m
{ 
    const int SIZE = 10; 
   int a[ SIZE ] = { 10, 2, 10, 4, 16, 6, 14, 8, 12, 10 }; 
   ostream_iterator< int > output( cout, " " ); 

   vector< int > v1( a, a + SIZE ); // copy of a 
   cout << "Vector v1 before replacing all 10s:\n             "; 
   copy( v1.begin(), v1.end(), output ); 

   // replace all 10s in v1 with 100 
    replace( v1.begin(), v1.end(), 10, 100 ); 
   cout << "\nVector v1 after replacing 10s with 100s:\n              "; 
   copy( v1.begin(), v1.end(), output ); 

}
