Yes, but if you make it so that the C++ compiler can't so easily remove the loop, then they are the 
same :)

int main(int argc, char *argv[])
{
     unsigned char doors = 0;
     //const unsigned int n = 100000000;
     unsigned int n = argc > 1 ? atoi(argv[1]) : 10000000;

<IMHO, that's almost always a worthless optimization for "real-world" code and even "good" 
benchmarks :)>.
