to overload

In C + +, we want to print the class information, need to overload overload We use code to explain: we define a person class that wants to print out the age attribute of the person class instance. Person { private: int age_; Public:

When processing memory allocations, C + + programmers use the new operator (operator new) to allocate memory and use the delete operator (operator delete) to free up memory. While this type of writing works well for most of the time, it's annoying
