C++ Unnamed classes


Example

Unlike a named class or struct, unnamed classes and structs must be instantiated where they are defined, and cannot have constructors or destructors.

struct {
    int foo;
    double bar;
} foobar;

foobar.foo = 5;
foobar.bar = 4.0;

class {
    int baz;
public:
    int buzz;
    
    void setBaz(int v) {
        baz = v;
    }
} barbar;

barbar.setBaz(15);
barbar.buzz = 2;
