XI`ANTECHNOLOGICALUNIVERSITY课程设计汇报课程名称:C语言程序设计专业:班级:姓名:学号:指导老师:成绩:年1月5日题目:学生成绩管理系统思绪:先建立一个链表然后以链表为基础进行多种操作,设计学生成绩管理系统,经过主页显示,依据自己需求按主页中所显示步骤输入,删除,查找,插入,修改,统计学生信息。算法:关键算法为链表生成,插入,查找,排序算法。函数模块介绍:voidxuanze();//选择功效voidshuchu(structstudent*h);//输出voidtianjia(structstudent*h);//添加voidshanchu(structstudent*h);//删除voidchaxun(structstudent*h);//查询voidgenggai(structstudent*h);//更改主voidgxuehao(structstudent*p);//改学号voidgname(structstudent*p);//改姓名voidggaoshu(structstudent*p);//改高数成绩voidgyingyu(structstudent*p);//改英语成绩voidgc(structstudent*p);//改c语言成绩voidtongji();//统计主voidmax_average(structstudent*h);//统计平均分最高voidmax_gaoshu(structstudent*h);//统计高数最高voidmax_yingyu(structstudent*h);//统计英语最高voidmax_c(structstudent*h);//统计c语言最高voidbujige_average(structstudent*h);//统计平均分不及格学生信息voidbujige_gaoshu(structstudent*h);//统计高数不及格学生信息voidbujige_yingyu(structstudent*h);//统计英语不及格学生信息voidbujige_c(structstudent*h);//同意c语言不及格学生信息structstudent*creat(intn);//创建链表voidorder_two(structstudent*p,structstudent*q);//调换位置voidorder(structstudent*h);//排序源程序#include""#include""#include""#include<>#defineN30#defineM3typedefstructstudent{charnumber[10];charname[20];floatscore[M];floataver;floattotal;}STU;STUstu[N];intn;voidinputscore(void);voidsavescore(void);voidavergescore(void);voidtotal(void);voidlookscore(void);voidsearchscore(void);voidstatistic(void);voidadd(void);voidmodify(void);voiddelscore(void);voidsavescore(void);voidmenu(void);intmain(){shortintflag=0;menu();do{flag=1;switch(getch()){case'1':inputscore();break;/*输入成绩*/case'2':lookscore();break;/*查看成绩*/case'3':searchscore();break;/*查找成绩*/case'4':statistic();break;/*成绩统计*/case'5':modify();break;/*修改成绩*/case'6':add();break;/*添加成绩*/case'7':delscore();break;/*删除成绩*/case'8':savescore();break;/*保留成绩*/case'9':exit(0);/*退出成绩*/default:printf("输入有误\n");}printf("按任意键继续\n");getch();menu();}while(flag==1);}voidmenu(void){system("cls");printf("\t\t\n"); printf("\t\t学生信息管理系统\n");printf("\t\t\n"); printf("\t\t\n"); printf("\t\
