Buenas, tengo un problema con la parte final de este código, y es que quiero que el programa me lea todos los préstamos que he hecho, pero solo me sale 1, más concretamente el primero. Por ejemplo, yo en el programa pongo información sobre 4 películas que quiero para alquilar, pero al final, cuando le pido al programa que me lea los datos del fichero txt, solo me lee los de la primera pelicula. Quisiera saber que poner para que me lea toda la información de las películas, y no solo de la primera.
Por cierto, también hay un pequeño error, que es que desde el "nombre de la pelicula" hasta "subtitulos?" los datos de sus respectivas preguntas son de la primera pelicula, pero después, a partir de "minutos", los datos los recoge de la última película que puse.

Repito, lo único que me falla es la parte en el que el programa tiene que leer la información que hay en el fichero, es decir, la del inputFile.

Buenos días, tengo un problema urgente con un ejercicio de c++ que me cuesta solucionar. el ejercicio es el siguiente:
Escribir un programa que ofrezca las siguientes opciones:
1. Client data
2. Sale data
3. Invoice
4. Totals
5. Restart
0. Exit
El programa mostrará el menú hasta que el usuario elija la opción.. Por ahora lo que llevó es esto. Seguramente haya mucha cosa innecesaria. Si es así, me lo podéis decir. Espero respuesta.
Muchas gracias de antemano.
