C++中跨多个文件的类

// 基类
class BaseClass {
public:
    virtual ~BaseClass() = default;

    virtual void someMethod() = 0;
};

// 子类1
class Child1 : public BaseClass {
public:
    void someMethod() override {
        // 子类1的具体实现
    }
};

// 子类2
class Child2 : public BaseClass {
public:
    void someMethod() override {
        // 子类2的具体实现
    }
};

// 客户端代码
int main() {
    BaseClass* obj1 = new Child1();
    BaseClass* obj2 = new Child2();

    obj1->someMethod();
    obj2->someMethod();

    delete obj1;
    delete obj2;

    return 0;
}
