If a function or a variable exists in scope with the name identical to the name of a non-union class type, struct can be prepended to the name for disambiguation, resulting in an elaborated type specifier.
Example
struct Foo; // forward declaration of a struct
struct Bar // definition of a struct
{
Bar(int i) : i(i + i) {}
int i;
};
enum struct Pub // scoped enum, since C++11
{
b, d, p, q,
};
int main()
{
Bar Bar(1);
struct Bar Bar2(2); // elaborated type
}
