(For more on operator overloading, see introduction to operator overloading.) Operator new is used to perform all memory allocation when the new keyword is used, and operator delete is used to deallocate that m
New and delete operators Initialization of global variables Templates Cleanup code Range-based for loops Strict return In C++, thenewoperator is used to dynamically allocate memory and call the object's constructor, while thedeleteoperator is used to call the destructor and subsequently free the memo...
Beginning with Visual C++ 5.0, the compiler supports member array new and delete operators in a class declaration. For example:Copy // spec1_the_operator_delete_function2.cpp // compile with: /c class X { public: void * operator new[] (size_t) { return 0; } void operator delete[]...

C++ supports dynamic allocation and deallocation of objects using the new and delete operators. These operators allocate memory for objects from a pool called the free store. The new operator calls the special function operator new, and the delete operator calls the special function operator delete....

delete 運算子 C++ 使用new和delete運算子支援物件的動態配置與解除配置。 這些運算子會從稱為「可用儲存區」(也稱為「堆積」) 的集區配置物件的記憶體。new運算子會呼叫特殊函式operator new,而delete運算子會呼叫特殊函式operator delete。 如需C 執行階段程式庫和 C++ 標準程式庫中的程式庫檔案清單,請參閱CRT...
The new and delete operators The function operator new is responsible for allocating memory when a new expression is invoked. The new operator can be either a globally defined function or a static member function of a class. It is possible to overload the global operators new and delete. ...
