Hola!, soy nuevo en el foro y necesito ayuda!, he estado tratando de crear algun codigo para poder eliminar una posicion de un programa que me han pedido en la escuela, el problema esta en que por más que busco no puedo hacerlo! 
Este programa almacena datos de dferentes personas (alumnos) y los guarda en una posicion de memoria, necesito que cuando yo elimine a una persona los datos que se proporcionan tienen que desaparecer por completo, por ejemplo:
1.-Luis
2.-Eduardo
3.-Carlos
4.-Martín
Eliminando a la carlos:
1.-Luis
2.-Eduardo
4.-Martín
Creo que quedaria más claro si les muestro el codigo:
