Requisito previo: enfoque modular en la programación Declaración del problema : escribir un programa en C para implementar el pedido de alimentos con las siguientes funcionalidades:
- Iniciar sesión Registrarse
- Buscar por alimento
- Buscar por hoteles
- Confirmación de carrito y pedido
Enfoque y funcionalidad :
Funcionalidad de registro
Esta es la función principal para registrarse. Desde aquí llamamos a la función account_check() para validar las entradas. Las siguientes son las funcionalidades:
- Ingrese el nombre de usuario, la edad, el correo electrónico, la contraseña, confirme la contraseña y el número de teléfono móvil.
- Validar las entradas
- El nombre de usuario debe contener letras.
- La edad debe ser mayor y no igual a 0.
- El correo electrónico debe contener @, una coma y la longitud debe ser superior a 5.
- Las contraseñas deben contener una longitud entre 8 y 12 con al menos una letra mayúscula, minúscula, un número y un carácter especial. Tanto la contraseña como la contraseña de confirmación deben ser iguales.
- El número de móvil debe contener números y exactamente 10 dígitos.
Después de la validación exitosa de todos los campos de entrada, verifica si la misma cuenta ya existe o no a través de la funcionalidad account_check() .
Funcionalidad de inicio de sesión
Esta función implementa las funciones de inicio de sesión de nuestro proyecto. Mientras inicia sesión, el correo electrónico y la contraseña se validan y verifican si ya está registrado. Después del inicio de sesión exitoso, hay una opción para elegir las funcionalidades Search_by_food() o Search_by_hotels() .
Ordenar por Hotel
En esta funcionalidad, el pedido de comida se realiza después de seleccionar cualquier Hotel. Una vez seleccionado el hotel se despliega la lista de alimentos con sus respectivos costos. Una vez que se selecciona la comida, debe ir a la opción Seleccionar carrito para ordenar con éxito los alimentos.
Antes de ordenar por el hotel, inicialice algunos hoteles predeterminados que se nos dan localmente a través de estructuras en C para nuestra demostración. Una vez inicializados dinámicamente los hoteles y sus respectivos alimentos, se desplegará la lista de hoteles.
Ordenar por comida
Una vez seleccionado el hotel en el paso anterior, seleccione la comida e ingrese la cantidad de artículos a ordenar. Una vez realizada la selección de todos los alimentos se mostrará la cantidad total de alimentos seleccionados. Muévase a Seleccionar carrito para ordenar con éxito los alimentos.
Carro
Esta funcionalidad realiza lo siguiente:
- Muestra el costo total de tus pedidos.
- Confirma tu pedido y disfruta de tu comida.
