Final conclusion: arithmetic on a void* is illegal in both C and C++. GCC allows it as an extension, see Arithmetic on void- and Function-Pointers (note that this section is part of the "C Extensions" chapter of the manual). Clang and ICC likely allow void* arithmetic for the purposes...
*p = idx[0]; // it's undefined whether the value of idx[0] is written into ra[idx]});Finally, pointer arithmetic is not allowed to be performed on pointers to bool values since that will result in invalid pointers pointing to an unaligned data region....

This way, we can display the odd numbers using the pointer arithmetic on the console screen. Conclusion We conclude here that the pointer arithmetic is the most effective tool that performs different operations in C++. Make sure that the pointer increments or decreases the value of an array that...
Pointer arithmetic is valid only within the bounds of a single array, but C compilers are not required to check this. Remarkably, the subscript operator [] in C is actually defined in terms of pointer arithmetic: lines 2 and 4 are syntactic sugar for lines 3 and 5, respectively. More ...

Unbound is a validating, recursive, and caching DNS resolver. - Arithmetic on a pointer to void is a GNU extension. by fobser · Pull Request #768 · NLnetLabs/unbound
Since void is an incomplete type, it is not an object type. Therefore it is not a valid operand to an addition operation. Therefore you cannot perform pointer arithmetic on a void pointer. Notes Originally, it was thought that void* arithmetic was permitted, because of these sections of the...
Illegal arithmetic with pointers There are various operations which can not be performed on pointers. Since, pointer stores address hence we must ignore the operations which may lead to an illegal address, for example, addition, and multiplication. A list of such operations is given below. ...
