the inheritance diagram,type need to convert, you must design a new type class , and so on.Terms : Ning to pass -by-reference-to-const Replace pass-by- va LueWhen it comes to this clause, it is stated that the pass-through parameter is in the form of a copy by default in C + +. Which will create a temporary one.The copy. In most cases, it is more efficient to pass a constant reference directly, because it avoids the overhead of two of copies. But t

jumps to its implementation code.2. Key points-The message consists of a receiver, a method name, and a parameter. Send a message to an object is also equivalent to the object "Invoke method ".-All messages sent to an object are handled by the dynamic message dispatch system, which detects the corresponding partyand execute its code.12th: Understand the message forwarding mechanism (what happens when an object receives a message that cannot be read)1. Message forwarding is initiated when the ob

Dynamic Memory allocationc Dynamic memory allocation and deallocation use malloc (and its variants) and the free function, which only involves allocating and releasing memory, while C + + uses the new and delete keywords and automatically calls the object's constructor. malloc (and its variants)/free with, new/ Delete is used in conjunction with, not confusing.(Note: Individuals think that as long as you thoroughly understand the

Item m34: how to mix C ++ and C in the same program For many years, you have been worried about using C ++ in part during programming, just as using multiple compilers to generate programs in the age of all C programming. There is no way to program Multiple compilers, unless different compilers have the same implementa

Effective C # principle 1: Use attributes (property) as much as possible, rather than data members (field) Effective C # principle 2: Choose ReadOnly instead of const for your constants Effective C # Principle 3: Select is or as

SETJMP and longjmp non-localized jump statements: Nonlocal refers to, this is not similar to the normal C language goto statement, the statement in a function to jump, but on the stack to jump, may skip many call frames, and then return to the current function call path in a function. Use setjmp and longjmp where you need attention:1) setjmp and longjmp are used in combination, have their corresponding call order, setjmp before, longjmp in order to be

"Effective C # Quick Notes"-dynamic Programming in C #static types and dynamic types have strengths, and static types allow the compiler to help you find more errors, because the compiler can do most of the checking at compile time. C # is a static type of language, but it adds dynamic types of language features that c

the use of dynamic types in the public API Prefer to use static types in C # and minimize the scope of dynamic types. If you want to use dynamic features all the time, you should choose a dynamic language rather than C #. To use dynamic attributes in your program, try not to use them in a public interface, which restricts the dynamic type to a single object (or type). This seriesEffective

passing constant pointers is a better choice. But if you hit the STL again, and the iterators and function objects are all based on the C language pointers, then back to the original rule: the value of the pass is better than the reference.
