Hi,
I have a very basic doubt about associativity and precedence of
operators. I am not a computer science person and may find it quite
weird.
Consider an expression

printf("%d", a);

I'm trying to get a good understanding of how unary operators work and
have some questions about the following test snippets.
int *p;
~!&*++p--;
It doesn't compile, why? The problem seems to be the ++, the compiler
says: "Error: invalid l-value in increment".
int i = 10;
~!*&i++;

Associativity in C takes two forms: left to right and right to left. I
think the K&R book lacks something...
For example, *p++, since the associativity is from right to left, do
this expression means *(p++)? I think I am wrong. (so, associativity
is not for operand?)
But for *++p, right to left associativity means *(++p) is correct.
So by definition of associativity, I guess it only applys on grouped

For most users, this new feature is actually very convenient. If you want to control the update process,...
