vector iteration

[mmgh]

Hello,

This is a simplified code. Do you think can I write the code like that or there is a better way of doing that.

  class A {
    private:
      std::vector<int>  a_;
      std::string       c_;
    public:
      // ...
  };
  
  using Aiterator = typename std::vector<A>::iterator

  class B {
    private:
       std::vector<class A> d_;
       double               e_;
    public:
       // ...
  };

  using Biterator = typename std::vector<B>::iterator

  class C{
     private:
        std::vector<class B> b_;
     public:
       C();
      ~C();
       Biterator findA(int val);
  };

  Biterator findA(int val){
   
    for (const auto& BB : b_){
  
        Aiterator ab = BB.d_.begin(), ae = BB.d_.end();
        return std::find_if(ab, ae, val
                           {
                              return (val == BB.a_.getfunction());
                           })
    }

  }

[is there] a better way of doing that?

It depends on that you're trying to do and why. Can you describe the problem? You're creating a vector of vectors of vectors, which could get very large very fast. There may be an easier way.
