C++ keyword: struct

Usage

• declaration of a compound type

• 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
}
