The members and base classes of a struct are public by default, while in class, they default to private. Struct and class are otherwise functionally equivalent.They are however used in different places due to semantics. a struct is more like a data structure that is used to represent data. class, on the other hand, is more of a functionality inclined construct. It mimics the way things are and work.

Dicts are hash tables. No tree searching is used. Looking up a key is a nearly constant time(Amortized constant) operation, regardless of the size of the dict. It creates the hash of the key, then proceeds to find the location associated with the hashed value. If a collision listed address is encountered, it starts the collision resolution algorithm to find the actual value.This causes dictionaries to take up more space as they are sparse.

This activation mode supports activating the selected objects even if it results in inconsistent affected objects. For example, if you choose to activate an object A that is used by B and C, and it causes inconsistencies in B and C but you can choose to go ahead with the activation of A.

Difference Between Struct and Typedef Struct in C++

In C++, there is no difference between 'struct' and 'typedef struct' because, in C++, all struct/union/enum/class declarations act like they are implicitly typedef'ed, as long as the name is not hidden by another declaration with the same name.Though there is one subtle difference that typedefs cannot be forward declared. So for the typedef option, you must include the file containing the typedef before it is used anywhere.

There are similar rules for native mobile apps and application. Only domain needs are to be added to white list in PhoneGap or Cardova.The device acts as a server and can access content from URL .If PhoneGap is used then domains are added to whitelist or a wildcard.While dealing with a native application, you expect to make requests from file://, instead of from https://. However, a request is not made across the HTTP protocol, so the same rules do not apply.Making requests from native mobile app, will allow you to make requests to any domain without any major issues.
