explicit operator names

Explicit operators

These are keywords for bitwise and logical operators. Non-U.S. programmers without keyboard characters like &, |, ^, and so on, were forced to use C’s horrible trigraphs, which were not only annoying to type, but obscure when reading. This is repaired in C++ with additional keywords:

Keyword

Meaning

and

&& (logical and)

or

|| (logical or)

not

! (logical NOT)

not_eq

!= (logical not-equivalent)

bitand

& (bitwise and)

and_eq

&= (bitwise and-assignment)

bitor

| (bitwise or)

or_eq

|= (bitwise or-assignment)

xor

^ (bitwise exclusive-or)

xor_eq

^= (bitwise exclusive-or-assignment)

compl

~ (ones complement)

If your compiler complies with Standard C++, it will support these keywords.




I tried with MSVC .Net 2003 and failed to compile!

Visual Studio doesn't support these keywords, unfortunately. You may have to define them manually (#define and &&, etc).

Code:

---

#include <iso646.h>

---

Works in Visual C++ 2005 don't know about others.

Or rather, for C++, #include <ciso646>. Visual Studio doesn't support these keywords the way it is supposed to, i.e., without including <ciso646>.
