Now we have such a lump of code:[CPP]View Plaincopy std::vectorint> arr; // ... For (std::vectorint>::iterator iter = Arr.begin (); ITER! = Arr.end (); ++iter) { // ...   } The ugly and poorly maintained

1. Usage ScenariosThe common language runtime controls the physical layout of a data field's class or structure in managed memory. StructLayoutAttribute attribute to control the unmanaged layout of the type.">However, if you want to pass the type to

　　"Data Structure" modeOften some components have specific data structures internally, and if the client program relies on these specific data structures, it will greatly disrupt the reuse of the components. In this case, it is an effective solution
