Use transform to make the numbers in a list go from a certain range

  
#include <algorithm>
#include <cstdlib>
#include <functional>
#include <iostream>
#include <list>

using namespace std;

int main( )
{
   list<int> data( 100000 );

   // create random numbers
   generate( data.begin(), data.end(), rand );

   // make them go from 0 to 200
   transform( data.begin(), data.end(), data.begin(),bind2nd( modulus<int>(), 201 ) );

   // make them go from -100 to 100
   transform( data.begin(), data.end(), data.begin(),bind2nd( minus<int>(), 100 ) );


}
