You still still not reading from the file correctly. You have your input file formatted in a certain way, so you must read it in a certain way.

Please consider:

#include <iostream>
#include <fstream>

using namespace std;

int main() {
  ifstream infile;
  infile.open("books.txt");
  if(!infile) {
    cerr << "Unable to open file.\n";
    exit(1);
  }
  string parse; // collecting substr from this string
  while(getline(infile, parse)) {
    // Find the delim positions
    size_t delimPos[5]; // there are 5 semicolons per line
    delimPos[0] = parse.find(';');
    for(int i = 1; i < 5; i++) {
      delimPos[i] = parse.find(';', delimPos[i-1]+1);
    }
    string bookID, author, bookTitle, isbn, price, quantity;
    bookID = parse.substr(0, delimPos[0]);
    author = parse.substr(delimPos[0]+1, delimPos[1]-delimPos[0]-1);
    bookTitle = parse.substr(delimPos[1]+2, delimPos[2]-delimPos[1]-2);
    isbn = parse.substr(delimPos[2]+2, delimPos[3]-delimPos[2]-2);
    price = parse.substr(delimPos[3]+2, delimPos[4]-delimPos[3]-2);
    quantity = parse.substr(delimPos[4]+2);

  }
  return 0;
}
