全部! 我有一些類層次結構 class A {public: virtual void foo(int, T*) = 0; virtual void foo1(int, T*) = 0;};
class B : public A {public: void foo(int, T*) override; void foo1(int, T*) override;};
class C : publi
我需要通過一個標準的函數指針稱爲成員函數,所以我試圖抽象的東西是這樣的: class Sample {
public:
virtual void doSomething(void) = 0;
};
class A : public Sample {
void doSomething(void); // details omitted
};
class B :
我只是迷惑不解以下幾點: struct InterfaceABC {
virtual int printPolymorphic(int a) {
return a;
}
}
struct WithInterfaces : public InterfaceABC {
virtual int printPolymorphic(int a) { retur
