1. The corresponding new and delete statements must adopt the same form. What are the errors in the following statements?String * stringarray = new string [100];...Delete stringarray;
Everything seems to be in order-a new corresponds to a delete-but there is a big mistake hidden: The running status of the program will not be guessed. At least 99 of the 100 string objects pointed to by stringarray will not be correctly destroyed, because their destructor will never be called.

Decorator mode in Design Mode
The decorator mode is also called the packaging mode. It is an alternative to the inheritance relationship by extending the object functions in a transparent way to the client. The most typical example of using the decorator mode is the various Java IO streams.

Mode definition: The combination mode allows you to combine objects into a tree structure to express the "Overall/partial" hierarchy. The combination allows the customer to process individual objects and object combinations in a consistent manner.
In this mode, you can create a tree structure to process nested menus and menu item Groups in the same structure. By placing menus and items in the same structure, we create an "Overall/partial" hierarchy, which is an object tree consisting of menus an

an inline function, the compiler must generate a function body for this. How can the compiler generate a pointer to a non-existent function? Inline void F () {...} // same as aboveVoid (* PF) () = F; // pf points to FInt main (){F (); // inline call to FPF (); // non-inline call to F through pf...}This situation seems ridiculous: F calls are inline, but under the old rule, each compilation unit that obtains the f address still generates a static copy of this function. (Under the new rule, no ma

But since there is an arrays. Sort sorting method in the Java package, why not use it when there are few
