Hi,
I am facing a violation in a line of my C++ code, where the function is returning a pointer to a structure and i am indexing the returned pointer as below:
f(x)[0].value;
The AUTOSAR violation states the "array indexing is the only form of pointer arithmetic".
Is the reason for violation because we are returning a structure pointer inside of f(x)? and not a array pointer?
Regards
Kunal

Hi Kunal,
The reason is, structure pointer violates the following compliance rules of ANSI C:
17.1 (required): Pointer arithmetic shall only be applied to pointers that address an array or array element.
17.4 (required): Array indexing shall be the only allowed form of pointer arithmetic.
Therefore, the solution to this issue is to use the "-allow-ptr-arith-on-struct" option and treat the orange as safe.
Hope this helps!
