Difference between 'struct' and 'typedef struct' in C++?

Question

In C++, is there any difference between:

struct Foo { ... };

and:

typedef struct { ... } Foo;

Answer 1

Struct is to create a data type. The typedef is to set a nickname for a data type.

Answer 2

There is no difference in C++, but I believe in C it would allow you to declare instances of the struct Foo without explicitly doing:

struct Foo bar;
