计算机技术基础C语言课程设计设计报告题目：期末成绩管理及查询系统学院：电气与电子工程学院专业：电气工程及其自动化班级：090307姓名：张晨 指导教师： 设计日期：2010年7月4日题 目：期末成绩管理及查询系统选题背景：本程序实现一个简单的数据管理系统，用户可以先输入数据信息，程序再通过逻辑运算，判断是否可获奖学金。用户可以进行简单的查找，但无法进行模糊搜索。思路流程：通过年份比较算出年龄，再通过月份和日期的比较，判断是否是周岁，决定年龄是否减一。通过switch语句进行科目选择，用冒泡法对各科成绩进行排序，再次并通过switch语句进行单人选择。通过逻辑运算，判断是否可获奖学金。解决问题主要方法：主要运用for循环，以及scanf语句进行赋值。运用if-else语句进行判断。利用switch-case语句进行查找。利用goto语句，实现多次循环操作。程序流程：i=0iN输入十组数据真i+假调用库函数 ，定义结构体及字符常量l=0lbstdl.age-真真(stdl.DATE.month=b)&(stdl.DATE.dayc)假stdl.age-输出数据i+假输入科目代码代码值赋给letter选择真假12345表达式一将表达式一stdi.s.MZstdj.s.MZMZ改为JSJ将表达式一stdi.s.MZstdj.s.MZMZ改为HX将表达式一stdi.s.MZstdj.s.MZMZ改为YY表达式五输入dd=1输出字符串break真 假i=0真iN-1j=i-1jN真stdi.s.MZstdj.s.MZ值交换真j+i+为sum赋值选择1234567890nextsubject第一的信息第三的信息第二的信息第四的信息第五的信息第七的信息第六的信息第十的信息第八的信息第九的信息表达式1假假假k=0stdk.s.MZ60u=0stdk.s.JSJ60v=0stdk.s.HX60w=0stdk.s.YY60x=0u&v&w&x=0输出stdk.s.fellowship=Nstdk.s.fellowship=Y真真真真真假假假假假k+kN真假表达式五程序原源代码：#define NAMESIZE 20#define ADDRSIZE 100#define N 10struct subjectfloat MZ;float JSJ;float HX;float YY;float score;char fellowship;struct birthdayint year;int month;int day;struct studentint age;char nameNAMESIZE;char sex2;char addressADDRSIZE;struct birthday DATE;struct subject s;struct student std10;main()int i;int j;int a;int b;int d;int c;int l;int num;struct student change;int k;int u,v,w,x;int letter;for(i=0;iN;i+)printf(%dn,i+1);printf(sex: name:address:n);scanf(%s%s%s,stdi.sex,,stdi.address);printf(year-month-dayn);scanf(%d%d%d,&stdi.DATE.year,&stdi.DATE.month,&stdi.DATE.day);printf(MZ:JSJ:HX:YY:n);scanf(%f%f%f%f,&stdi.s.MZ,&stdi.s.JSJ,&stdi.s.HX,&stdi.s.YY);printf(Today:year-month-dayn);scanf(%d%d%d,&a,&b,&c);for(l=0;lb)stdl.age-;if(stdl.DATE.month=b)&(stdl.DATE.dayc)stdl.age-;printf(age:%dtname:%sn,stdl.age,);loop:printf(Please input first letter.(m=1,j=2,h=3,y=4,f=5,g=0)n);scanf(%d,&letter);switch(letter)case 1: for(i=0;iN-1;i+) for(j=i+1;jN;j+) if(stdi.s.MZstdj.s.MZ) change=stdi;
