Need help reading a text file into parallel arrays-CodePudding

I must have a function that reads card information from a text file (cards.txt) and insert them to parallel arrays in the main program using a pointer. I have successfully read the text file, but cannot successfully insert the info to the arrays. Can anyone help me please?

#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;
  }
}

CodePudding user response：

The main problem is that you have two sets of arrays, one in main, and one in readCards. You need one set of arrays in main and to pass those arrays (using pointers) to readCards. Like this

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)
{
    ...
}
