Declaración del problema : escriba un programa C para crear un software para el sistema de gestión de exámenes que pueda realizar las siguientes operaciones:
- Agregar/Eliminar los Detalles de los Estudiantes
- Seguimiento de asistencia de los alumnos
- Establecer/Editar criterios de elegibilidad para exámenes
- Verifique los estudiantes elegibles para los exámenes
- Imprimir todos los expedientes de los alumnos
Enfoque : La idea es formar una función individual para cada operación. Todas las funciones se unifican junto con los casos de cambio para formar software. A continuación se muestra la ilustración de las funciones:
- ejecutar(): esta función mostrará las opciones disponibles para el software y realizará la siguiente funcionalidad utilizando las declaraciones de cambio .
Funcionalidad:- Agregar detalles del estudiante
- Mostrar estudiantes elegibles
- Eliminar registro de estudiante
- Actualizar los criterios de elegibilidad
- Imprimir detalles de los estudiantes
- add(): esta función que obtiene los datos del usuario y actualiza la lista de los estudiantes. Mientras agrega al estudiante a la lista, verifique la singularidad del número de registro del estudiante. Los detalles de los estudiantes que se agregarán son:
- Nombre de estudiante
- Número de rollo
- Estado de las tarifas
- Registro de asistencia del estudiante
- elegibleStudents(): esta función muestra el porcentaje de asistencia anterior requerido para los exámenes y obtiene los datos del usuario y actualiza la elegibilidad para los exámenes. También actualiza el estado de la tarifa requerida para la elegibilidad de los exámenes iterando sobre la Lista de los registros de los estudiantes y para cada estudiante, verifique que el porcentaje de asistencia esté por encima del porcentaje requerido y el estado de la tarifa del estudiante.
- print_student(): esta función itera sobre la lista de estudiantes e imprime los detalles del estudiante.
- eliminar(): esta función obtiene el número de registro del estudiante para eliminar el registro del estudiante y actualizar la lista del estudiante.
A continuación se muestra el programa para ilustrar las funcionalidades anteriores:
