Post-Increment

This example is bad. Don’t do this:

#include <iostream>
using namespace std;

int main() {
   int n = 1;
   cout << ++n * ++n << endl;
}

Don’t do this, either:

#include <iostream>
using namespace std;

int main() {
   short nums[] = {1, 2, 3, 4};

   short *p = nums;
   cout << *p++ << ' ';
   cout << *p++ << '\n';

   p = nums;
   cout << *p++ << ' ' << *p++ << '\n';
}
