Getting the input from the file as string and also integer C++ - c++

Question

I have a text file. I have a text file consisting of member data. I am developing a program where we can get the member data from the file. After searching in the internet, I have searched a way to read all the data from the file as char array. But I want to change it where upon reading from file I want the data to be string and also integer.
name, icno, email, phone_number, acc_num, password ( read from file AS STRING )
month, year ( read from file AS INTEGER )
Content of Membership.txt

There are so many things completely wrong in your program that I do recomend to you:
Delete and start from scratch.
There is no meaningful fix possible. There is even a goto. And you MUST stop using C-Style arrays with some agic dimension in C++. And C++ has many things to make your live easier. Simply use them.
Please find below a C++ solution.
You can copy and paste it and stay as you are, or, you take 3 hours and google all constructs and try to understand and learn and become a better programmer. Your choise.
#include <iostream>
#include <fstream>
#include <string>
#include <iomanip>
#include <vector>
#include <regex>
#include <iterator>
#include <algorithm>
const std::regex re{ R"(\|)" };
struct Member {
// Memeber data
std::string name{};
std::string icno{};
std::string email{};
std::string phoneNumber{};
std::string accountNumber{};
std::string password{};
int month{};
int year{};
// Extractor operator
friend std::istream& operator >> (std::istream& is, Member& m) {
// Readone complete line
if (std::string line{}; std::getline(is, line)) {
// Split it into parts
std::vector parts(std::sregex_token_iterator(line.begin(), line.end(), re, -1), {});
// assign parts to member data
if (parts.size() == 8) {
m.name = parts[0]; m.icno = parts[1]; m.email = parts[2]; m.phoneNumber = parts[3]; m.accountNumber = parts[4]; m.password = parts[5];
m.month = std::stoi(parts[6]); m.year = std::stoi(parts[7]);
}
}
return is;
}
};
// Filename for member data
const std::string fileName{ "r:\\Membership.txt" };
int main() {
// Open the data file and check, if it could be opened
if (std::ifstream fileStream{ fileName }; fileStream) {
// Read complete source file, parse it and get all data
std::vector memberData(std::istream_iterator<Member>(fileStream), {});
// We want the user to give 3 trials to enter valid data
constexpr unsigned int MaxTrials = 3u;
unsigned int numberOfTrials{};
// A valid input will stop the loop immediately
bool validInputgiven{};
// Now, try to get the correct input
while (not validInputgiven and numberOfTrials < MaxTrials) {
// Get an acoount number
std::cout << "\nEnter a account number: ";
std::string account{};
std::cin >> account;
// Check, if the account number is in the member data
if (std::count_if(memberData.begin(), memberData.end(), [&](const Member& m) { return m.accountNumber == account; }) > 0) {
// Account info wasOK. Get the password
std::cout << "\nEnter your password: ";
std::string password{};
std::cin >> password;
if (std::count_if(memberData.begin(), memberData.end(), [&](const Member& m) { return m.accountNumber == account and m.password == password; }) > 0) {
// Valid data found
validInputgiven = true;
std::cout << "\n\nEverything OK. Data validated.\n\n";
}
}
// Next try
++numberOfTrials;
if (not validInputgiven and numberOfTrials < MaxTrials) std::cout << "\nInvalid input. Please try again\n\n\n";
}
if (not validInputgiven ) std::cout << "\nToo many wrong tries. Aborting . . .\n\n\n";
}
else std::cerr << "\n\nError. Could not open source file '" << fileName << "'\n\n";
}
