C++
#include <iostream>
using namespace std;
// Structure Account
struct Account {
  // Stores the name
  string name;
  // Stores the account number
  int number;
  // Stores the total amount
  double balance;
};
// Function check_account
void check_account(struct Account p[], int arr[], int size) {
  // Traverse array
  for (int i = 0; i < size; i++) {
    // Check if balance less than 500
    if (p[i].balance < 500) {
      // Store account number 
      arr[i] = p[i].number;
    } else {
      // Store -1
      arr[i] = -1;
    }
  }
}
// print_arr function
void print_arr(int arr[], int size) {
  for (int i = 0; i < size; i++) {
    cout << arr[i] << endl;
  }
}
// print_Account function
void print_Account(struct Account p[], int size) {
  for (int i = 0; i < size; i++) {
    cout << "Person" << i + 1 << " details:" << endl;
    cout << p[i].name << endl;
    cout << p[i].number << endl;
    cout << p[i].balance << endl;
    cout << endl;
  }
}
// main function
int main() {
  // Declare array of type int
  int arr[3];
  // Declare structure array
  struct Account p[3];
  // Intialize structure array
  p[0] = {"John",578328,890};
  p[1] = {"Alex",908210,430.2 };
  p[2] = {"Kim",165216,98.5};
  // Call print_Account function
  print_Account(p, 3);
  // Call check_account function
  check_account(p, arr, 3);
  // Call print_arr function
  print_arr(arr, 3);
  return 0;
}
