将函数中的对象添加到动态指针数组中

问题描述

课程：

主席;

BigChair; （没有天真）



Chair.h：

int _bigChairsLength;

BigChair ** _bigChairs;



Chair.cpp：

Classes:
Chair;
BigChair; (no innherit)

Chair.h:
int _bigChairsLength;
BigChair** _bigChairs;

Chair.cpp:

void Chair::AddBigchair(string name, string color) // It must get params and not BigChair
{
     BigChair** temp = _bigChairs;
     _bigChairsLength++;
     _bigChairs = new BigChair*[_bigChairsLength];

     for (int i=0; i<_bigChairsLength - 1; i++)
     {
         _bigChairs[i] = temp[i];
     }

     delete [] temp;

     BigChair newBigChair(name, color);
     _bigChairs[_bigChiarsLength - 1] = &newBigChair;
              // (pointer to function variable??? how to add?
}

推荐答案

_bigChairs[_bigChiarsLength - 1] = new BigChair(name, color);

这是一个同性恋作业还是面试问题？这是如此基本。

PS：使用合适的STL容器（例如 vector ）而不是指针指针。例如 std :: vector< BigChair> （或 std :: vector< BigChair *> ，取决于你的用法）。整个函数将折叠为 mvVector.push_back（BigChair（名称，颜色））; 。

Is this a homweork assignment or an interview question? This is so basic.

PS: use a suitable STL container (e.g. a vector) instead of a pointer of pointer. E.g. std::vector<BigChair> (or std::vector<BigChair*>, depends on you usage). The whole function would collaps to mvVector.push_back(BigChair(name, color));.
