string variables and system commands part 2

Im trying to get a string variable into a system command but it wont work, whats wrong with my code?

char cmd[200],comp[256],message[256];
cout<<" Enter computer name: 008-";
cin.getline(comp,256,'\n');cin.get();
cout<<" Enter message: ";
cin.getline(message,256,'\n');cin.get();
sprintf(cmd,"net send 008-%s",comp," %s",message);
cin.get();

sprintf follows basic printf syntax:

printf( const char* formatstring, ... )


So:

sprintf(cmd,"net send 008-%s",comp," %s",message);

should be

sprintf( cmd, "net send 008-%s %s", comp, message );
