Why should I not try to use “this” value after “delete this”? http://stackoverflow.com/questions/1866461/why-should-i-not-try-to-use-this-value-after-delete-this after you delete it this or any other pointer is that the hardware could and some older machines did trap trying to load an invalid.. into a register. Even though it may be fine on all modern hardware the standard says that the only thing that you can do to a invalid..

Does the size of an int depend on the compiler and/or processor? http://stackoverflow.com/questions/2331751/does-the-size-of-an-int-depend-on-the-compiler-and-or-processor no importance at all. The compiler is free to implement a hardware abstraction layer of any thickness and emulate absolutely anything... efficiency considerations imposed by the underlying hardware. In that sense the size of basic types will depend on the hardware.. In that sense the size of basic types will depend on the hardware i.e. each basic type will be based on some representation immediately..
