for(loops)



int main(void) {
  for(int n=0;n!=50;n++)
    cout << "Hello, world no. %d\n" << n << endl;
}

int main(void) {
  for(int n=0;n!=50;++n)
    cout << "Hello, world no. %d\n" << n << endl;
}

int main(void) {
  for(int n=0;n!=50;n=n+1)
    cout << "Hello, world no. %d\n" << n << endl;
}

int main(void) {
  for(int n=0;n!=50;n+=1)
    cout << "Hello, world no. %d\n" << n << endl;
}

The second code runs fastest, followed by the first code, then the third and fourth tied. I though these were logically the same? Why the speed difference.
