Remember: Stores the Newd object in a smart pointer in a separate statement. If you do not, once an exception is thrown, it is possible to cause an imperceptible resource leak. intPriority ();voidProcesswidget (std::tr1::shared_ptr

Remember: If you use [] in a new expression, you must also use [] in the corresponding delete expression. If you do not use [] at new, be sure not to use [] at delete. string New string ; string New string [...] delete stringPtr1; //

Resources1. C++primer #7 classA virtual table belongs to a class, not to a specific object, and a class requires only a single virtual table. All objects of the same class use the same virtual table.To specify a virtual table for an object, the

Conditions (look at each of the basic types for a few bytes first):voidSize_ () {printf ("char type:%d\n",sizeof(Char)); printf ("int type:%d\n",sizeof(int)); printf ("Float type:%d\n",sizeof(float)); printf ("Double type:%d\n",sizeof(Double));

To address the problem of C + + memory leaks, C++11 introduced smart pointers (smart Pointer).The principle of smart pointers is to accept a well-applied memory address, construct a smart pointer object stored on the stack, there is an important
