In codeproject, i found a interesting program which implements a meaning of unit ,like

unsigned long long operator"" s(unsigned long long n)
{
    return n + 1;
}
int main()
{
    int x = 16s;
}

x will be 17, so interesting. can someone tell me what magic this is?

This is one of those "you can only find out if you already know" problems. Given how effective googling for `operator""` is, I don't think it was the best choice of syntax. – molbdnilo Aug 27 '18 at 07:10
For this sort of problems it's better to rely on search engines other than google https://stackoverflow.com/q/4685615/817643 – StoryTeller - Unslander Monica Aug 27 '18 at 07:13

@molbdnilo Should google-ability be a criteria of syntax design? – Aug 27 '18 at 07:15
If you concern about *privacy*, you shouldn't use google at all! – Aconcagua Aug 27 '18 at 07:21
