学生体测信息管理系统
废话不多说，我们直接进入正题。
（C语言）
我们要完成一个学生体测信息管理系统，实现以下功能：
1、学生数据录入
2、学生信息修改
3、学生信息删除
4、学生成绩查询
5、学生不及格项目查询
6、各项目通过率汇总
UI界面
首先让我们完成UI界面
#include<stdio.h>
int choice;//定义全局变量choice，方便函数调用，用于储存用户所选择的功能
void UI()
{
printf("\t ------------------------------------\n");
printf("\t| 学生体测信息管理系统 |\n");
printf("\t| 0.退出本系统 |\n");
printf("\t| 1.输入学生数据 |\n");
printf("\t| 2.修改学生数据 |\n");
printf("\t| 3.删除学生数据 |\n");
printf("\t| 4.查询学生成绩 |\n");
printf("\t| 5.查询不合格科目 |\n");
printf("\t| 6.查询体测合格率 |\n");
printf("\t ------------------------------------\n");
printf("请选择功能：");
scanf("%d", &choice);
printf("\n");
}
退出系统
再来写一下这个最简单的操作吧！
这个就没必要写单独的函数了，直接放在主函数中
printf("感谢使用本系统，祝您生活愉快！");
return 0;
输入学生数据
让我们思考一下该如何储存学生数据呢？
没错我们可以使用结构体来对学生数据进行储存，
查阅了相关资料C语言中汉字其实是可以用字符串存储的，每个汉字占用两个字节。。。。
struct Student
{
char name[20];//姓名
char stuNum[20];//学号
char department[20];//院系
int sex;//性别
float height;//身高
float weight;//体重
float BMI; //体重指数
float VC;//肺活量
float jump;//跳远
float runShort;//短跑
float runLong;//长跑
int count;//引体向上，仰卧起坐个数
//记录成绩
int BMI_score;
int VC_score;
int jump_score;
int runShort_score;
int runLong_score;
int count_score;
};
接着来完成数据录入操作
简单的完成当然很容易，但我们如何让我们的程序更加完美呢？
我们便要完成判断输入数据是否合法。（防止有些人喜欢乱输使程序出错）
另外我们如果只需读取单个数据，用户却输入了一堆，
经过测试与查阅相关资料，我们知道这些多余的数据并不会消除，
而是会保存在输入流中进而被下一个scanf读取，
这时我们便可以使用while (getchar() != '\n');巧妙的完成对输入流的清空，
所以我们在每一次scanf函数后重复一遍重复此操作
#include<string.h>
int i, j;//用于循环
int flag;//用于情况标记
int choice;//记录功能选择
struct Student students[100];//最大学生量可以自定义
int nowSum = 0;//目前已存学生数
int nowSum_index;//用于
void InputData()
{
int choice1 = -1;
int flag;//用于情况标记
printf("是否开始录入新的学生数据？\n");
printf("<1:开始录入,0:取消录入> :");
scanf("%d", &choice1);
while (getchar() != '\n');
while (1)
{
if (choice1 == 1)//录入开始
{
choice1 = -1;
printf("姓名：");//录入姓名
scanf("%s", students[nowSum].name);
while (getchar() != '\n');
printf("院系：");//录入院系
scanf("%s", students[nowSum].department);
while (getchar() != '\n');
printf("学号：");//录入学号
while (1)

flag = 1;
scanf("%s", students[nowSum].stuNum);
while (getchar() != '\n');
//判断是否合法参考了我自己学校学号的规则，第一位为大写字母，之后八位为数字，一共九位，可以自己修改
if (strlen(students[nowSum].stuNum) != 9)
{
printf("数据错误，请重新输入:");
flag = 0;

main函数编写
进行事件循环
int main()
{

void PassRate();
while (1)

数据存储到本地
我们接下来想要完成下面两件事
1、关闭程序时将数据保存到本地
2、每次打开程序都将本地的数据读入
void load()
{
FILE* fp;
fp = fopen("data.txt", "r");
while(！feof(fp))
{
fscanf(fp, "%s", students[nowSum].name);
fscanf(fp, "%s", students[nowSum].stuNum);
fscanf(fp, "%s", students[nowSum].department);
fscanf(fp, "%d", &students[nowSum].sex);
fscanf(fp, "%f", &students[nowSum].height);
fscanf(fp, "%f", &students[nowSum].weight);
fscanf(fp, "%f", &students[nowSum].BMI);
fscanf(fp, "%f", &students[nowSum].VC);
fscanf(fp, "%f", &students[nowSum].jump);
fscanf(fp, "%f", &students[nowSum].runLong);
fscanf(fp, "%f", &students[nowSum].runShort);
fscanf(fp, "%d", &students[nowSum].count);
fscanf(fp, "%d", &students[nowSum].BMI_score);
fscanf(fp, "%d", &students[nowSum].VC_score);
fscanf(fp, "%d", &students[nowSum].jump_score);
fscanf(fp, "%d", &students[nowSum].runLong_score);
fscanf(fp, "%d", &students[nowSum].runShort_score);
fscanf(fp, "%d", &students[nowSum].count_score);
nowSum++;
}
}
void save()
{
FILE* fp;
fp = fopen("data.txt", "w");
fprintf(fp, "%d\n", nowSum);
for (i = 0; i < nowSum; i++)
{
fprintf(fp, "%s\n", students[i].name);
fprintf(fp, "%s\n", students[i].stuNum);
fprintf(fp, "%s\n", students[i].department);
fprintf(fp, "%d\n", students[i].sex);
fprintf(fp, "%f\n", students[i].height);
fprintf(fp, "%f\n", students[i].weight);
fprintf(fp, "%f\n", students[i].BMI);
fprintf(fp, "%f\n", students[i].VC);
fprintf(fp, "%f\n", students[i].jump);

fprintf(fp, "%d\n", students[i].runLong_score);
fprintf(fp, "%d\n", students[i].runShort_score);
fprintf(fp, "%d\n", students[i].count_score);
}
}
//我们将数据保存在data.txt中
在进行测试时我发现，无论文件为空时feof()第一次也还是会返回1，
这就导致了当文件为空时，students[0]会读入空数据，
经过思考我想到了一种可行的办法：
在文件开头记录下学生总数来限制读取次数；
我们便只需在最初创建data.txt时在开头保存一个0就行了，
接下来对代码进行修改，代码就不放了。

至于代码为什么这么长，当然是有很多重复的代码了，
其实就是因为我菜，只会写屎山代码
想优化自己去优化吧！！！
代码写的脑子发懵........
别忘记了先在与代码相同的目录下创建文本哦。
