將對象加載到指向對象的指針陣列

Question

我試圖加載競爭對象（啓動器）在主要創建一個排序器對象，存儲競爭對手的讀取作爲讀入對象的指針數組中的對象。由於某種原因，它只讀取傳入的第一個對象。如何將主函數中的所有對象讀入類中的存儲？

ranker.cpp：

#include "ranker.h" 
#include "competitor.h" 
#include <stdlib.h> 

Ranker::Ranker(int lanes) { 
    athlete = new Competitor*[lanes]; // fix 
    numAthletes = 0; 
    maxAthletes = lanes; 
} 

int Ranker::addList(Competitor* starter) { 
    if (numAthletes < maxAthletes && &starter != NULL) { 
     athlete[numAthletes] = starter; 
     numAthletes++; 

     return numAthletes; 
    } 
    else 
     return 0; 
} 

Competitor* Ranker::getLane(int lane) { 
    for (int i = 0; i < numAthletes; i++) { 
     if (athlete[i]->getLane() == lane - 1) { 
      return athlete[i]; 
     } 
    } 
} 

Competitor* Ranker::getFinish(int position) { 
    switch(position) { 
     case 1: 
      return athlete[3]; 
      break; 
     case 2: 
      return athlete[2]; 
      break; 
     case 3: 
      return athlete[1]; 
      break; 
     case 4: 
      return athlete[0]; 
      break; 
    } 
} 

int Ranker::getFilled() { 
    return numAthletes; 
} 

Ranker::~Ranker() { 
    delete athlete; 
} 

ranker.h：主要功能

#ifndef _RANKER_H 
#define _RANKER_H 

#include "competitor.h" 

class Ranker { 
private: 
Competitor** athlete; 
    int numAthletes; 
    int maxAthletes; 
public: 
    Ranker(int lanes); 
    int addList(Competitor* starter); 
    Competitor* getLane(int lane); 
    Competitor* getFinish(int position); 
    int getFilled(); 
    ~Ranker(); 
}; 

#endif 

部分：

for (int i = 0; i < lanes; i++) 
    rank.addList(starters[i]); 

Answer 1

使用std::vector<Competitor>來存儲你的競爭對手，並與它們添加push_back()。
