How could I modify this program to output the tokens in reverse order?

Code:

#include <iostream>
using std::cin;
using std::cout;

#include <cstring>

void output( const int, char [] );

int main() {
   
   const int Size = 50;
   char words[ Size ] = { '\0' }; 
   
   cin.getline( words, Size );
  
   output( Size, words );
   
   cin.get();
   return 0;
}

void output( const int Size, char sentence[] ) {
   
   char *strToken;
   int control = Size;
   
   strToken = strtok( sentence, " " );
   cout << '\n';
   
   while ( (strToken != NULL) ) {
      cout << strToken << '\n';
      strToken = strtok( NULL, " " );
   }
   
}

I've tried numerous things which haven't worked. Is pointer arith needed? Thanks.
