Unusual use of the Ternary Operator

I'm a newbie to C, I understand why ternary operators can be useful, less code than if/else blocks.

I have been given some C code to maintain, and one thing I've noticed is the previous programmer used ternary operators like this

myInt = (!myInt) ? MACRO1 : MACRO2;

Does this accomplish exactly the same thing as this:

myInt = myInt ? MACRO2 : MACRO1;

Is this just a style thing? Perhaps it makes sense to think "if not" myInt, instead of "if"?

Yes, you are correct. It seems as though the originator of that code wanted to make the expression slightly more confusing than it needed to be.

I prefer the second example as it is not using reverse logic, therefore easier to understand and less clutter.

myInt = myInt ? MACRO2 : MACRO1;

Yes, this code accomplishes exactly the same thing. It just depends on the logic used when writing the condition - so it can be chalked up to style (i.e. whichever is easier for you to think).
