int main() { MyClass* cPtr = new MyClass(); delete cPtr } Run Code Online (Sandbox Code Playgroud) 分别.这个程序运行得很好.但是,我无法理解的是,如何在没有任何参数的情况下调用new运算符,而在其定义中它具有类似"size_t size"的函数参数.有没有一点,我在这里失踪?谢谢. c++ operator-overlo...
What is function overloading and operator overloading? - Function overloading: A feature in C++ that enables several functions of the same name can be defined with different types of parameters or different number of parameters... Use of this pointer ...

OK, let's look at how to overload new operator in MyClass. classMyClass { public: void*operatornew(size_t,Pool*);// static function, implicitly. void*operatordelete(void*);// static function, implicitly. }; void*MyClass::operatornew(size_taSize,Pool*aPool) ...
下面是一个简单的示例程序: ```cpp #include class Array { private: int* data; int size; public: Array(int n) { size = n; data = new int[size]; } ~Array() { delete[] data; } int& operator[](int index) { if (index < 0 || index >= size) { std::cout << \Error: ...
Overloaded Operator == Ref: C++关系运算符重载 声明关键字 operator,以及紧跟其后的一个c++预定义的操作符,举例如下: // 申明关键字 classperson{private:intage;public: person(inta){this->age=a; } inlinebooloperator==(constperson &ps)const;
- A template function overloads itself as needed. But we can explicitly overload it too. Overloading a function template means having different sets of function templates which differ in their parameter list. - Consider following example : ...
