c++ file reading into memory - c++

Question

i'm trying to load the file into an array when the program starts so i can
modify or search in it i don't know if my code works or not ( it's not reading the file )i have the file
and there's two books in
i have tried to debug it but couldn't find the problem the code works
but it think there's a problem with the load() function i don't know what
my code :
#include <iostream>
#include <string>
#include <fstream>
#include <iomanip>
using namespace std;
struct books{
//identfying books with all needed things
int id, status;
string title, p_name, p_address;
string date;
string aut_name, aut_nationality;
}newbook[10000], aut[10000];
int i = 0;
void load(){
ifstream myfile("books.txt", ios::in);
while (myfile >> newbook[i].id >> newbook[i].title >> newbook[i].p_name >> newbook[i].p_address >> aut[i].aut_name >> aut[i].aut_nationality >> newbook[i].date >> newbook[i].status)
i++;
}
void search_for_book(){
int temp = 0;
int idx;
cout << "enter the ID of the book you're looking for : ";
cin >> idx;
for (int srh = 0; srh < i; srh++){
if (newbook[srh].id == idx){
cout << setw(10) << "book found :" << endl;
cout << "title :" << newbook[srh].title << endl;
cout << "publisher name : " << newbook[srh].p_name << endl;
cout << "publisher address" << newbook[srh].p_address << endl;
cout << "author name :" << aut[srh].aut_name << endl;
cout << "author Nationality :" << aut[srh].aut_nationality << endl;
cout << "publish Date :" << newbook[srh].date << endl;
cout << "status :" << newbook[srh].status << endl;
temp++;
break;
}
else
srh++;
}
if (temp == 0){
cout << "couldn't find book" << endl << endl;
}
}
int main(){
load();
char choice;
cout << "enter your choice (3)";
cin >> choice;
if (choice == '3'){
search_for_book();
}
}
note :*( there are other functions like adding new book but not necessary to write )
*(i'm new to c++ don't really know how to read file into memory but i'm trying)
this is the code to save data into file :
void add_new_book_5(){
int booksnumber;
books newbook[1000], aut[100];
cout << "how many books you want to add ? ";
cin >> booksnumber;
cout << "what books you want to add :" << endl;
d_base.open(path, ios::out | ios::app);
for (int i = 0; i < booksnumber; i++){
cout << "id please : "; cin >> newbook[i].id;
cout << "title : "; cin.ignore(); getline(cin, newbook[i].title);
cout << "publisher name :"; getline(cin, newbook[i].p_name);
cout << "publisher address : "; getline(cin, newbook[i].p_address);
cout << "author" << " name : "; cin.ignore(); getline(cin, newbook[i].aut_name);
cout << "Nationality : "; getline(cin, newbook[i].aut_nationality);
cout << "Publish date :"; getline(cin, newbook[i].date);
cout << "How many copies of " << newbook[i].title << " "; cin >> newbook[i].status;
system("cls");
d_base << newbook[i].id << "\ " << newbook[i].title << "\ ";
d_base << newbook[i].p_name << "\ " << newbook[i].p_address << "\ ";
d_base << newbook[i].aut_name << "\ " << newbook[i].aut_nationality << "\ ";
d_base << newbook[i].date << "\ " << newbook[i].status << endl;
}
d_base.close();
cout << setw(76) << "Books Have Been Saved Sucessfully" << endl;
}
