Restrict is introduced by the C99 standard, which can only be used to qualify and constrain pointers, and to indicate that pointers are the only and initial way to access a data object. That is, it tells the compiler that all operations that modify what the pointer points to in-memory must be modified by that pointer. Instead of being modified by other means (other variables or pointers) , the advantage is that it helps the compiler to better optimize the code and generate more efficient assemb

We generally use the new modifier on Class Members to redefine non-Virtual members inherited from the base class. This does not mean we should do this. Redefinition of non-virtual methods can lead to ambiguous behaviors. For example Code The vast majority of developers think that their behavior is the same (assuming that two classes have an inheritance relationship ): Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeH
