Explain this please.....

Question

int(*p)(char*p)[ ](++). what is the meaning of this ?

Answer 1

Let's see...

int (*p)(char *p)[]

declares p as a pointer to a function, which takes a pointer to a character as an argument/parameter of the function. This function has return type of int[].

Now, look at operator precedence for C/C++.

http://en.cppreference.com/w/cpp/language/operator_precedence

"Associativity specification is redundant for unary operators and is only shown for completeness: ... ", "... unary postfix operators always associate left-to-right (a[1][2]++ is ((a[1])[2])++)".

That said, this code seems to be missing segments? At the current point, it does not make sense to place postfix increment operator there. C also does not allow function declarators to return array type:

The C standard (ISO/IEC 9899:2011): 6.7.6.3 Function declarators (including prototypes)

Constraints
1 A function declarator shall not specify a return type that is a function type or an array type.
