24.13.2.Use std::replace to replace elements in vector by value
#include <iostream>
using std::cout;
using std::endl;

#include <algorithm>
#include <vector>
#include <iterator>

int main()
{
   int a10 1021041661481210 };
   std::ostream_iterator< int > outputcout, " " );

   std::vector< int > v1a, a + 10 )// copy of a
   cout << "Vector v1 before replacing all 10s:\n   ";
   std::copyv1.begin(), v1.end(), output );

   // replace all 10s in v1 with 100
   std::replacev1.begin(), v1.end()10100 );
   cout << "\nVector v1 after replacing 10s with 100s:\n   ";
   std::copyv1.begin(), v1.end(), output );

   cout << endl;
   return 0;
}
Vector v1 before replacing all 10s:
   10 2 10 4 16 6 14 8 12 10
Vector v1 after replacing 10s with 100s:
   100 2 100 4 16 6 14 8 12 100
