Nested structures

Question

The following code compiles on a C++ compiler.

#include 
int main()
{
    struct xx
    {
        int x;
        struct yy
        {
                    


        

Answer 1

Well, cstdio needs to be referred as stdio.h. As for the structure, the struct-keyword is not required in C++.

You don't really define struct members, but pointer members, so it seems plausible that it should work in either case.
