c++11 introduced useful specifier override explicitly override base virtual function. explicit hiding ? for example, consider code: struct a: b { void f(); } if there virtual void b::f() code cause implicit overriding function. if there non-virtual void b::f() code cause hiding function. that is, meaning of code depends on existence , virtuality of void b::f() . question. how explicitly hide base function? want error if try hide virtual function. such override guard ensure there is virtual base function same prototype, need guard ensure there no virtual base function same prototype. epic fail example: #include <stdio.h> struct b { void f() {printf("hello\n");} void g() {f();} }; struct a: b { void f() {g();} }; int main() { a; a.f(); return 0; } the program print "hello". if make b::f() virtual program cause segmentation fault (infinite recursion). may real problem if b class third-party ,
