在C++中处理多个对象依赖的最佳方法是什么？

#include<iostream>

class DependencyA {
public:
    void doSomething() {
        std::cout << "Dependency A is doing something"<< std::endl;
    }
};

class DependencyB {
public:
    void doSomething() {
        std::cout << "Dependency B is doing something"<< std::endl;
    }
};

class MyClass {
private:
    DependencyA* a;
    DependencyB* b;

public:
    // 构造函数注入
    MyClass(DependencyA* a, DependencyB* b) : a(a), b(b) {}

    void doSomething() {
        a->doSomething();
        b->doSomething();
    }
};

int main() {
    DependencyA a;
    DependencyB b;
    MyClass obj(&a, &b);
    obj.doSomething();

    return 0;
}
