C++ keyword: struct - cppreference.com
From cppreference.com
Usage
- If a function or a variable exists in scope with the name identical to the name of a non-union class type,
structcan 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 }
