comment on c++ output code

#include

struct temp

{

int a;

int b;

int c;

};

int main()

{

struct temp p[] = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};

return 0;

}

1. No compile time error, generates an array of structure of size 3

2. Compile time error, illegal declaration of a multidimensional array

3. No compile time error, generates an array of structure of size 9

4. Compile time error, illegal assignment to members of structure

Thanks!
