According to the C and C++ standards, in pointer arithmetic, the resulting address should remain strictly on the boundary of a single array object (or follow it immediately). Adding or subtracting a pointer shifts it by a multiple of the data type size it points to. For example, there is...
6.2.5-19: The void type comprises an empty set of values; it is an incomplete type that cannot be completed. 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 v...
The error is that pointer arithmetic operations may only involve pointers to object types, but void is by definition an incomplete type. This only works because GNU C goes against the standard and defines (for convenience's sake)sizeof(void) == 1in these cases, as ifvoid*was actuallychar*...

On any modern computer the value of a pointer is a memory address (typically a virtual memory address). When you add one to a pointer, it's value (aka the memory address) is incremented by the sizeof the pointed to type. Example: TYPE* p = SOME_ADDRESS; // The value of p is no...
The processor also includes an instruction fetcher 8, an instruction register 10, a register file 12 and an instruction pointer 14 all of which operate under the control of a control unit 16 of the processor. The register file comprises a set of registers each having a predetermined bit ...
