Consider the below syntax :
#include <iostream>
int main() {
std::cout << 1["ABC"] << std::endl;
}
The program outputs B which leads me to believe that it behaves as "ABC"[1]. Is that possible, what is the reason behind this ?

This is tagged C, but also work for C++. – YSC Mar 28 '18 at 08:40

2This is how C has been designed more than 40 years ago; C++ inherited this behaviour. – axiac Mar 28 '18 at 08:41

Somewhat coincidentally, it's ultimately because of [B](https://en.wikipedia.org/wiki/B_(programming_language)). – molbdnilo Mar 28 '18 at 08:42

2Don't really understand the downvote. This is well posed and isn't exactly obvious nor intuitve. – Passer By Mar 28 '18 at 08:42

4@Bathsheba [This one](https://stackoverflow.com/questions/14378650/integer-indexed-with-a-string-in-c) directly use string literal. – user202729 Mar 28 '18 at 08:50

@user202729: Touche. If I reopen, could someone close to that? (I can't do it if I've voted to reopen). – Bathsheba Mar 28 '18 at 08:51

@user202729 I tried some simple queries, the duplicates aren't easy to find unless you already know what you're looking for. – Passer By Mar 28 '18 at 08:51

@liliscent: Wow, didn't know I could hammer reopen then hammer close. I'll take steps to ensure the power doesn't go to my head. I know this dupe target is C, but the langages are similar in this respect. Note though that "ABC" is a `char[4]` literal in C but a `const char[4]` literal in C++, – Bathsheba Mar 28 '18 at 08:54
