If I have a struct like struct account { int account_number; }; Then what's the difference between doing myAccount.account_number; and myAccount->account_number; or isn't there a difference? If there's no difference, why wouldn't you just use the . notation rather than ->? …

2011年1月15日 · The first declaration is of an un- typedef ed struct and needs the struct keyword to use. The second is of a typedef ed anonymous struct, and so we use the typedef name.

The difference between struct and class keywords in C++ is that, when there is no specific specifier on particular composite data type then by default struct or union is the public keywords that merely considers data hiding but class is the private keyword that considers the hiding of program codes or data.

2017年1月21日 · Our code involves a POD (Plain Old Datastructure) struct (it is a basic c++ struct that has other structs and POD variables in it that needs to get initialized in the beginning.) Based one what I...

2017年12月16日 · Difference between Structs and Classes: Struct are value types whereas Classes are reference types. Structs are stored on the stack whereas Classes are stored on the heap. Value types hold their value in memory where they are declared, but a reference type holds a reference to an object in memory.

2011年11月20日 · typedef struct node LLIST; That means LLIST is a type, just like int or FILE or char, that is a shorthand for struct node, your linked-list node structure. It's not necessary - you could replace LLIST with struct node in all of those spots - but it makes it a bit easier to read, and helps hide the implementation from pesky end-users.

Treating a struct like a C++ class - in C++ structures are actually special types of classes, where all members are public (unlike a standard C++ class where all members are private if not specified otherwise explicitly) as well as that when using inheritance they default to public:

2022年2月25日 · Note that structure tags are in a separate namespace from typedef names, so it is legitimate to use typedef struct tagname tagname;. The body of the structure can appear between the two occurrences of tagname.

I have a struct as follows, with a pointer to a function called "length" that will return the length of the chars member. typedef struct pstring_t { char * chars; int (* length)(); } PStri...

In C++, struct s do not have a comparison operator generated by default. You need to write your own: bool operator==(const MyStruct1& lhs, const MyStruct1& rhs) { return /* your comparison code goes here */ }
