Answer 1

Functionally, they are the same in C; I'm not sure about other languages where ugly things like operator overloading come into play.

Stylistically, the latter is extremely counter-intuitive and personally I find it extremely ugly. The point is to get the compiler to throw an error when you accidentally write = instead of ==, but good compilers have an option to warn you about this anyway so it's unnecessary.
