Need to figure out conio.h for a book program, which Idk how to

Question

I'm writing a book program that enables the user to Add and Find books to a library. Now, I need to figure out how to receive keyboard input from the user using conio.h/any other alternative. So that if the user presses '1', the AddMenu() gets called, but if he/she presses 2, FindMenu() gets called. Here is the code:

#include <iostream>
#include <conio.h>

using namespace std;


class Book {
public:
    string title; //title of da book
    double sepnum; //unique identification code (ex. 1111, 0009, etc.)
};

void AddMenu() {

    Book book1;

    cout << "********ADD MENU********" << endl;
    cout << endl;
    cout << endl;
    cout << "Enter Book Name:" << endl;
    cin >> book1.title;
    cout << "Enter Book Callsign (Ex: 0001, 5672):" << endl;
    cin >> book1.sepnum;
    cout << "Succesfully added" << endl;
    cout << endl;
    cout << "************************" << endl;

}

void FindMenu() {

}

int main()
{
    cout << "**********MENU**********" << endl;
    cout << endl;
    cout << endl;
    cout << "1. Add Book" << endl;
    cout << "2. Find Book" << endl;
    cout << endl;
    cout << "************************" << endl;

    return 0;
}
