c語言課程設(shè)計報告-學(xué)生信息管理系統(tǒng)

題目：學(xué)生信息管理系統(tǒng)一、需求分析任務(wù)要求：自學(xué)C語言中有關(guān)鏈表及外部文件的內(nèi)容，設(shè)計學(xué)生信息管理系統(tǒng)。具體要求如下：?建立學(xué)生信息，信息至少包括名字、性別、年齡、學(xué)號、系別、家庭信息等內(nèi)容；?能夠提供添加、刪除和修改學(xué)生信息等功能；?能將通訊錄保存在文件中；?能夠按指定方式輸出學(xué)生信息。系統(tǒng)功能需求分析：1、為存儲學(xué)生信息，需定義一個結(jié)構(gòu)體類型，成員名字、性別、年齡、學(xué)號、系別、家庭信息等，并建立鏈表，定義該結(jié)構(gòu)體類型的指針，用于指向各結(jié)點；2、分別建立具有添加、刪除、修改、查詢等功能的子函數(shù)，完成相應(yīng)功能，對程序?qū)崿F(xiàn)模塊化。這其中要用到對鏈表的刪除、插入等知識。刪除時用一結(jié)構(gòu)體指針指向鏈表的第一個結(jié)點，檢查該節(jié)點的值是否等于輸入的要刪除的學(xué)號，若相等就刪除，不相等則后移指針，直至表尾。插入時也要先找到相應(yīng)結(jié)點，再添加?！?、為實現(xiàn)存儲功能，需用到文件的相關(guān)函數(shù)，打開文件，將添加、修改或刪除的信息存入磁盤中。★4、為以表格的形式輸出文件，宏定義格式化輸出語句，指定輸出學(xué)生信息。二、概要設(shè)計系統(tǒng)總體設(shè)計框架對程序進(jìn)行模塊化，建立添加、修改、刪除、查找和顯示功能的子函數(shù)，各子函數(shù)中運用鏈表存儲數(shù)據(jù)。從主函數(shù)開始執(zhí)行，調(diào)用各個子函數(shù)，并運用文件相關(guān)知識將信息存入磁盤中。系統(tǒng)功能模塊圖：三、詳細(xì)設(shè)計主要功能模塊的算法設(shè)計思路如下1、查詢通訊錄信息(voidchakan())為開辟一個新單元輸入查詢關(guān)鍵字：讀取保存的文件數(shù)據(jù)輸入ASCLL字符：在鏈表中尋找相應(yīng)結(jié)點；調(diào)用輸出函數(shù)，輸出結(jié)點信息。2、添加信息函數(shù)(voidadd())定義指向結(jié)構(gòu)體變量的指針；移動指針，找到插入結(jié)點；在要插入的結(jié)點輸入信息；調(diào)用保存函數(shù)，打開文件，保存輸入信息。3、刪除信息函數(shù)(voiddel())定義指向結(jié)構(gòu)體變量的指針；用指針檢驗鏈表中是否有記錄，若沒記錄，返回主函數(shù)根據(jù)要修改的編號查找要刪除的結(jié)點；修改鏈表，刪除對應(yīng)結(jié)點。4、修改信息函數(shù)(voidxiugaiO)定義指向結(jié)構(gòu)體變量的指針；讀取保存的文件數(shù)據(jù)輸入ASCLL字符：用指針檢驗鏈表中是否有記錄，若沒記錄，返回主函數(shù)根據(jù)要修改的編號查找對應(yīng)結(jié)點；修改信息；（6）打開文件，保存修改記錄。5、保存信息函數(shù)（baocun（））（1）定義指向結(jié)構(gòu)體變量的指針；（2）用文件指針指向要讀寫的磁盤文件名，若沒有則新建此文件名（3）用指針檢驗鏈表中是否有記錄，若沒記錄，返回主函數(shù)：（4）打開文件，保存記錄：6、屏幕操作函數(shù)（voidstubent187（））（1）以一定格式輸出所想要的圖形：定義變量：（對整個程序定義全局變量）#include""#include""#defineSTUDENTID/*所有STUDENT都用ID來代替*/typedefstructnode/*定義結(jié)構(gòu)體*/{charming[50];/*名字*/charxing[50];/*性別*/charnian[50];/*年齡*/intxuehao;/*學(xué)號*/charxibie[50];/*專業(yè)*/charsushe[50];/*宿舍號*//*家庭地址*/charjia[50];/*家庭地址*/structnode*next;}ID;/*學(xué)生信息(變量名)*/ID*head=NULL;/*定義—個頭指針*/FILE*zhi;/*定義—個文件指針*/主菜單界面：(進(jìn)入屏幕界面的形式)voidstubent187()/*屏幕格式函數(shù)*/printf("*學(xué)生信息管理系統(tǒng)*\n");printf("**\n");printf("*請選擇：1:查看;2:添加;3:刪除;*\n")printf("*4:修改;0:退出系統(tǒng)*\n");printf("**\n");I廣/H\11\printf("*******************************************\n");printf(">>>>>>>>>>>>>輸入0~4數(shù)字<<<<<<<<<<<<<、n");return;}查看學(xué)生信息記錄：(對以保存在磁盤文件的學(xué)生信息進(jìn)行查詢voidchakan(){/*查看*/ID*t;t=head;t=(ID*)malloc(sizeof(ID));/*為t開辟—新單元*/if((zhi二fopen("","rb"))二二NULL)printf(“沒有此文件\n“)；else{printf("%10s%10s%10s%10s%10s%10s%10s\n","ming","xing","nian","xuehao","eng","sushe","jia");/*輸出一個屏幕格式*/while(!feof(zhi)){fscanf(zhi,"%10s%10s%10s%10d%10s%10s%10s\n",&t->ming,&t->xing,&t->nian,&t->xuehao,&t->xibie,&t->sushe,&t->jia);/*讀取保存的文件數(shù)據(jù)輸入ASCLL字符：*/printf("%10s%10s%10s%10d%10s%10s%10s\n",t->ming,t->xing,t->nian,t->xuehao,t->xibie,t->sushe,t->jia);/*以這形式輸出各個學(xué)生信息*/t->next=(ID*)malloc(sizeof(ID));t=t->next;}};}添加學(xué)生信息記錄：()voidadd(){chari;/*添加*/ID*t1,*t2;t1=t2=NULL;loop:t仁(ID*)malloc(sizeof(ID));/*為t1開辟—新單元*/printf("請輸入姓名：")；scanf("%s",&t1->ming);/*姓名*/
