In terms of structures, this means that the structure cannot have any private/protected members, user-provided constructors, base classes, or virtual member functions (see this great post for an explanation). There is no need to initialize storage arrays in Solidity. The downside of the previous method is that array can be initialized with hard-coded values, or the bigger the array needs to be, the bigger the initialization statement will be. Now, to make a 1D array of those pointers in static memory, we must follow the following syntax: We can access the pointers inside our array just like we access normal array elements. C99 and C++ allow the initializer for an automatic member variable of a union or structure type to be a constant or non-constant expression. To access any structure object, you need to combine array indexed and structure member accessing technique. This function returns a pointer of type void.
