None of the eight questions in page under FAQ link match question
asked, in my opinion. I suppose you could interpret the OP's question
to be a comparison between C struct and C++ class, but I read OP's
question as a comparison between C struct and C++ struct.

One difference between C struct and C++ struct is that C++ struct can
have methods inside. Another difference is that parts of C++ struct
can be "hidden" by being made private.

Since the only difference between a C++ struct and a C++ class is the
default access (public for struct, private for class), the explanation in
"what is a class" together with "what's the difference between the keywords
struct and class" should answer the question of the OP (assuming the OP
knows C structs).

I agree. Good point. With the above directions OP will be fine.

The syntax for using a struct is different in C than C++.

In C++ struct is a type, and can be referred to much like an int. Not so in
C.

Actually it is also a type, except that you have to prefix every use
of the name with the keyword "struct" unless you declare it as a
typedef.

As you say, of course, the syntax is different, but types in C have
different semantics than in C++ anyway.

struct A {
char x;
int y;
};

struct A A1;

struct A A2;
A2.x = 1;
A2.y = 600;

In C:
A1 = A2; <--- can do?
If i'm not wrong, must use memcpy() byte by byte.

In C++:
A1 = A2; <--- can do?
