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

Question

In C++, is there any difference between:

struct Foo { ... };

and:

typedef struct { ... } Foo;

Answer 1

An important difference between a 'typedef struct' and a 'struct' in C++ is that inline member initialisation in 'typedef structs' will not work.

// the 'x' in this struct will NOT be initialised to zero
typedef struct { int x = 0; } Foo;

// the 'x' in this struct WILL be initialised to zero
struct Foo { int x = 0; };
