The internal members of a struct are the same for both C and C++. However, a C struct has no member methods and is entirely public. A C++ struct, on the other hand, is public by default but otherwise works exactly the same as a class.Aside from object-oriented nature of the C++ struct, the major difference between the two is in the declaration.In C, you could declare a struct in a variety of ways:struct foo {...}; struct foo bar;struct foo {...} bar;typedef struct foo {...} bar;The above three lines are all functionally equivalent (although you can't use all three in the same namespace, of course). However, the explicit use of typedef is the preferred method in C, thus allowing new instances of the structure to be created without the need to continually use the struct keyword:typedef struct foo {...} bar;foo another_bar;foo yet_another_bar;In C++ the use of typedef is not necessary, so the declarations can use the more simplified form:struct foo {...} bar;foo another_bar;foo yet_another_bar;Note that typedef is not implied, it's simply not required. You can still use a typedef if you want, but it's existence is mostly for backward compatibility with C. In fact, the only time a typedef is ever required is when the tag name or instance name clash with a function name in the same namespace. Although its ultimately better to avoid name clashes altogether, a typedef will resolve the clash.
