需要幫助將文本文件讀入並行數組

Question

我必須有一個從文本文件（cards.txt）中讀取卡片信息並使用指針將它們插入主程序中的並行數組的函數。 我已成功讀取文本文件，但無法成功將信息插入數組。 任何人都可以幫助我嗎？

#include <iostream>
#include <stream>
#include <string>
using namespace std;

void readCards();

int main() {
  ifstream inputFile;
  const int SIZE = 10;
  int id[SIZE];
  string beybladeName[SIZE];
  string productCode[SIZE];
  string type[SIZE];
  string plusMode[SIZE];
  string system[SIZE];

  readCards();

  return 0;
}

void readCards() {
  ifstream inputFile;
  const int SIZE = 10;
  int id[SIZE];
  string beybladeName[SIZE];
  string productCode[SIZE];
  string type[SIZE];
  string plusMode[SIZE];
  string system[SIZE];
  int i = 0;

  inputFile.open("cards.txt");
  cout << "Reading all cards information..." << endl;
  if (inputFile) {
    while (inputFile >> id[i] >> beybladeName[i] >> productCode[i] >> type[i] >> plusMode[I] >>
      system[I]) {
      i++;
    }
    cout << "All cards information read." << endl;
  }
  inputFile.close();

  for (int index = 0; index < SIZE; index++) {
    cout << "#:" << id[index] << endl;
    cout << "Beyblade Name: " << beybladeName[index] << endl;
    cout << "Product Code: " << productCode[index] << endl;
    cout << "Type: " << type[index] << endl;
    cout << "Plus Mode: " << plusMode[index] << endl;
    cout << "System: " << system[index] << endl;
    cout << " " << endl;
  }
}

主要問題是您有兩組數組，一組在main中，一組在readCards中。 您需要main中的一組數組並將這些數組（使用指針）傳遞給readCards 。 像這樣

void readCards(int* id, string* beybladeName, string* productCode, string* type, string* plusMode, string* system);

int main()
{
    ifstream inputFile;
    const int SIZE = 10;
    int id[SIZE]; 
    string beybladeName[SIZE];
    string productCode[SIZE];
    string type[SIZE];
    string plusMode [SIZE];
    string system [SIZE];

    readCards(id, beybladeName, productCode, type, plusMode, system);

    return 0;
} 

void readCards(int* id, string* beybladeName, string* productCode, string* type, string* plusMode, string* system)
{
    ...
}
