Here are a few scenarios to discuss pointers.I. Pointers and variablesThe variable is the alias of the storage space, and the Access form is direct access.Pointers to access memory addresses are indirect accesses.Where to access memory using

Set V is the object of a vector,If V is non-null, then v.at (0) and v[0] are indistinguishable, taking the first value in the array;If V is empty, then v.at (0) throws an exception (exception std::out_of_range), indicating that the array subscript

3.2 Strategy (Policy mode)motivation: During the software build process, some objects use algorithms that can be varied and often changed, and if you encode them into an object, the objects become unusually complex, and sometimes supporting unused
