初学编程答辩用的学生信息管理系统
说明：在学习完C语言之后学院要求我们三人一组，做系统来答辩，其中有图书馆信息管理系统，学生信息管理系统，酒店管理系统可选择。当时我们组选择的是学生信息管理系统，由于时间匆忙，而且当时水平也不是很高，所以代码有些凌乱，不过功能上还是齐全的，其中有：从文件读取信息，从键盘读取信息，增加信息，删除信息，查找信息，排序，输出信息等。具体的以后运行一下就知道了。
以下是代码：
#include<stdio.h> //包涵基本的输入输出
#include<stdlib.h> //包涵控制循环退出等函数
#include<malloc.h> //开辟新节点的头文件
#include<string.h> //字符处理的头文件
#define LEN sizeof(struct node) //宏定义LEN---------后期程序稍简洁
#define HEADER1 " ┏━━━━━━━━━━━━━━━━━━━━━━━━━━━STUDENT━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┓\n"
#define HEADER11 " \t┃\t\t\t┏━━━━━━━┳━━━━┳━━━┳━━━━┳━━━━┳━━━━┳━━━━┳━━━━┓\t\t\t ┃\n"
#define HEADER2 " \t┃\t\t\t┃ 学号 ┃ 姓名 ┃C成绩 ┃数学成绩┃英语成绩┃ 总分 ┃ 平均分 ┃ 排名 ┃\t\t\t ┃\n"
#define HEADER3 " \t┃\t\t\t┣━━━━━━━╋━━━━╋━━━╋━━━━╋━━━━╋━━━━╋━━━━╋━━━━┫\t\t\t ┃\n"
#define FORMAT " \t┃\t\t\t┃%-14s┃%-8s┃ %-4d┃ %-5d┃ %-5d┃ %-6d┃ %-7.2f┃ %-5d┃\t\t\t ┃\n"
#define DATA pt->data.num,pt->data.name,pt->data.cgrade,pt->data.mgrade,pt->data.egrade,pt->data.total,pt->data.ave,pt->data.ranking
#define END " \t┃\t\t\t┗━━━━━━━┻━━━━┻━━━┻━━━━┻━━━━┻━━━━┻━━━━┻━━━━┛\t\t\t ┃\n"
#define HEADEng " \t┃\t\t\t┃ Num ┃ Name ┃ C ┃ Math ┃English ┃ Total ┃Average ┃ Ranking┃\t\t\t ┃\n"
