Weirdest quirk of your main prog lang?

Quirk of C++ (also C I think)
int array[]={1,2,3,4,5};
int temp = array[0]; //valid access
int temp2 = 0[array]; // also valid

C++ is a member of the Foot Shooters Club languages of choice.

Also, this weekend I learned you cannot have a vector of references:

int[] == int*
a[b]==(a+b)
a+b==b+a

Similar to JS many quirks make sense once you understand how they occur in the first place.

@fuckwit not quite I think. The actual pointer offset operation is p + b. But since p is a pointer to type t, this offset operation considers the size of t in the offset operation.
