Beginning with Visual C++ 5.0, the compiler supports member array new and delete operators in a class declaration. For example: 复制 // spec1_the_operator_new_function2.cpp class MyClass { public: void * operator new[] (size_t) { return 0; } void operator delete[] (void*) { } }...

The most common way to overload an operator in a class is to use a member function. The function declaration takes this form: returnType operatorsymbol(parameter list) {// body of overloaded member function} The name of the function is operator keyword followed by the operator symbol, such ...
