1、 總體功能分析

實(shí)用的圖書館管理系統(tǒng)應(yīng)該至少包括一下功能：

1、上傳：新進(jìn)圖書以及基本信息的輸入

2、刪除：舊圖書以及基本信息的刪除

3、顯示：顯示圖書館已有的所有圖書

4、查找：查詢要借閱的圖書信息

5、借閱：實(shí)現(xiàn)用戶辦理借閱手續(xù)

6、歸還：實(shí)現(xiàn)用戶辦理歸還手續(xù)

系統(tǒng)以菜單方式工作使界面友好，易于操作。

2、建立相關(guān)屬性

由于系統(tǒng)設(shè)計(jì)的是一些圖書和讀者的信息存儲(chǔ)，因此，需要定義一個(gè)數(shù)據(jù)結(jié)構(gòu)來(lái)存儲(chǔ)相關(guān)信息。

首先需要建立一個(gè)圖書類、圖書數(shù)據(jù)庫(kù)類、讀者類以及讀者數(shù)據(jù)庫(kù)類，并定義圖書和讀者的各種屬性。

#include "iostream"
#include "string"
#include "conio.h"
using namespace std;

struct Date{//日期結(jié)構(gòu)
    int m_nYear;//年
    int m_nMonth;//月
    int m_nDay;//日
};

struct Reader{//讀者結(jié)構(gòu)
    string name;//讀者姓名
    Date bro;//借出時(shí)間
    Date back;//歸還時(shí)間
};

struct Book{//圖書結(jié)構(gòu)
    int m_nBook_Number;//圖書編號(hào)
    string m_strTitle;//書名
    string m_strWroter;//作者
    int m_nMoreNum;//當(dāng)前在圖書館數(shù)量
    int m_nTotalHoldNum;//圖書館共計(jì)數(shù)量
    string m_sttrComment;//圖書介紹
    Reader reader[20];
};

struct Info{//借書信息結(jié)構(gòu)
    Info *m_pParentPoint;//前驅(qū)節(jié)點(diǎn)
    Book *m_oBookInfo;//對(duì)應(yīng)圖書信息
    Info *m_pNextPoint;//后繼節(jié)點(diǎn)

};

3、圖書館菜單

程序開始運(yùn)行，將顯示選擇菜單，供用戶選擇需要的功能，用戶根據(jù)需要，輸入不同的數(shù)字來(lái)選擇相應(yīng)功能。

int  Select_Menu(){
    //圖書管理系統(tǒng)主界面
    cout << "--------------------------------------------------" << endl << endl;
    cout << "              圖  書  館  管  理  系  統(tǒng)             " << endl;
    cout << "                     主  菜  單                     " << endl << endl;
    cout << "                    1.上傳圖書" << endl;
    cout << "                    2.下架圖書" << endl;
    cout << "                    3.顯示圖書" << endl;
    cout << "                    4.借閱圖書" << endl;
    cout << "                    5.歸還圖書" << endl;
    cout << "                    6.退出系統(tǒng)" << endl << endl;
    cout << "               請(qǐng)選擇菜單項(xiàng)：（1-6）" << endl;
    cout << "--------------------------------------------------" << endl;
    int id = 0;//編號(hào)
    cout << "請(qǐng)輸入您的選擇：";
    cin >> id;
    return id;
}

4、圖書上傳

將圖書信息添加到圖書館中

Book *InputNode(){
    //上傳圖書
    Book *p = new Book;//動(dòng)態(tài)分配一片大小為sizeof(Book)字節(jié)的空間，并將該內(nèi)存空間的起始位置賦值給p
    system("cls");//清屏
    fflush(stdin);//清楚以前的輸入
    cout << "請(qǐng)輸入圖書編號(hào)："; cin >> p->m_nBook_Number;
    cout << "請(qǐng)輸入圖書："; cin >> p->m_strTitle;

    cout << "請(qǐng)輸入圖書介紹："; cin >> p->m_sttrComment;
    for(int i = 0; i < 20; i++){//初始化書本結(jié)構(gòu)成員中相關(guān)讀者指針內(nèi)容為空
        (p->reader[i]).name = '\0';
    }
    return p;//返回成功讀入的書本信息
}

Info *Insert_BookInfo(Info *bth){
    //上傳圖書
    int flag, k, x;
    cout << "請(qǐng)輸入您想上傳的圖書編號(hào)：";//按照書本編號(hào)進(jìn)行查找
    cin >> x;
    Info *p = Sreach(bth, x, &k, &flag);
    if(flag == 1){//找到直接對(duì)已有的數(shù)量進(jìn)行修改
        cout << "當(dāng)前圖書館內(nèi)擁有這本書" << p->m_oBookInfo->m_nMoreNum << "本，您想在增加一本" << p->m_oBookInfo->m_strTitle << "書？(Y/N)" << endl;
        char ch;
        cin >> ch;
        if(ch == 'Y' || ch == 'y'){
            p->m_oBookInfo->m_nMoreNum++;
            p->m_oBookInfo->m_nTotalHoldNum++;
            cout << "增加后圖書館內(nèi)擁有這本書" << p->m_oBookInfo->m_nMoreNum << "本，一共擁有" << p->m_oBookInfo->m_nTotalHoldNum << "本" << endl;
        }
        return bth;
    }
    //圖書管內(nèi)未找到這本圖書編號(hào)
    Book * r = InputNode();
    if(bth == NULL){//當(dāng)bth指針為空時(shí)，需要對(duì)其進(jìn)行單獨(dú)處理，鏈表表頭內(nèi)存的分配
        bth = new Info;
        bth->m_pParentPoint = NULL;
        bth->m_oBookInfo = r;
        bth->m_pNextPoint = NULL;
    }
    else {
        //說(shuō)明存在頭指針
        p = bth;
        while (p->m_pNextPoint != NULL)
            p = p->m_pNextPoint;
        Info *q = new Info;
        q->m_oBookInfo = r;
        q->m_pNextPoint = NULL;
        q->m_pParentPoint = p;
        p->m_pNextPoint = q;
    }
    return bth;
}

5、 刪除圖書

將圖書信息從圖書館中刪除

Info *Delete_BookInfo(Info * bth){
    //刪除圖書
    int flag, k, x;
    cout << "請(qǐng)輸入您想刪除的圖書編號(hào)：";//按照書本編號(hào)進(jìn)行查找
    cin >> x;
    Info *p = Sreach(bth, x, &k, &flag);
    if(flag == 0){//為查找圖書編號(hào)
        cout << "圖書館內(nèi)并沒(méi)有這本書?。?！" << endl;
        return bth;
    }
    else{
        if(p == NULL){//確保當(dāng)前操作是有效的，防止出現(xiàn)非法操作
            cout << "查找錯(cuò)誤" << endl;
            return bth;
        }
        else {
            cout << "你想刪除的圖書信息如下：" << endl;
            cout << "圖書編號(hào)：" << p->m_oBookInfo->m_nBook_Number << endl;
            cout << "書名：" << p->m_oBookInfo->m_strTitle << endl;

            if(ch == 'Y' || 'y'){
                if(p->m_pNextPoint != NULL && p->m_pParentPoint != NULL){//夾在鏈表中間的節(jié)點(diǎn)
                    Info *Left = p->m_pParentPoint;//將要?jiǎng)h除節(jié)點(diǎn)的前驅(qū)節(jié)點(diǎn)指向賦值給前驅(qū)結(jié)點(diǎn)指針變量

                }
                else if(p->m_pParentPoint == NULL){//首結(jié)點(diǎn)的前驅(qū)為空，處理首結(jié)點(diǎn)刪除操作
                    if(p->m_pNextPoint == NULL){//說(shuō)明只有一個(gè)結(jié)點(diǎn)
                        delete p->m_oBookInfo;
                        p->m_oBookInfo = NULL;
                        delete p;
                        p = NULL;

                    }
                    bth = p->m_pNextPoint;
                    bth->m_pParentPoint = NULL;

                    p->m_pNextPoint = NULL;
                    p->m_pParentPoint = NULL;
                    delete p->m_oBookInfo;

                }
            }
        }
    }
}

6、 查找圖書

根據(jù)輸入的圖書編號(hào)，是心啊圖書的查找。

Info *Sreach(Info *bth, int x, int *k, int *flag){
    //搜索圖書
    Info *p = bth;
    *flag = 0;
    while(p){
        if(p->m_oBookInfo->m_nBook_Number == x){//尋到相同的圖書編號(hào)
            *flag = 1;
            return p;
        }
        else {
            *flag = 0;
        }
        if(p->m_pNextPoint != NULL) {
            p = p->m_pNextPoint;
        }
        else{
            break;
        }
    }
    return bth;
}

7、顯示圖書信息

顯示圖書館中所有的圖書信息。

void Output_BookInfo(Info * bth){
    //輸出圖書信息
    system("cls");
    Info *p = bth;
    while (p){
        cout << "圖書編號(hào)：" << p->m_oBookInfo->m_nBook_Number;
        cout << "書名：" << p->m_oBookInfo->m_strTitle;

        cout << "圖書共計(jì)數(shù)量：" << p->m_oBookInfo->m_nTotalHoldNum;
        cout << "這本圖書簡(jiǎn)介：" << p->m_oBookInfo->m_sttrComment << endl;
        p = p->m_pNextPoint;
    }
}

8、圖書借閱

根據(jù)輸入的相關(guān)信息，實(shí)現(xiàn)借閱

void Borrow_TheBook(Info *bth){
    //圖書借出
    system("cls");
    int flag, k, x, i = 0;
    cout << "請(qǐng)輸入您想借閱的圖書編號(hào)：";//按照書本編號(hào)進(jìn)行查找
    cin >> x;
    Info *p = Sreach(bth, x, &k, &flag);
    if(flag == 1){
        Book *r = p->m_oBookInfo;
        cout << "你想借閱的圖書信息如下：" << endl;
        cout << "書名：" << p->m_oBookInfo->m_strTitle << endl;

        cout << "您確定借閱嗎？(Y/N)" << endl;
        char ch;
        cin >> ch;
        if(ch == 'Y' || ch == 'y'){
            if(r->m_nMoreNum == 0) cout << "對(duì)不起，本書 已經(jīng)全部借出···" << endl;
            else{
                system("cls");
                for(i = 0; i < 20; i++)
                    if((r->reader[i]).name[0] == '\0') break;
                cout << "請(qǐng)輸入借閱者的姓名：";cin >> (r->reader[i]).name;
                cout << "請(qǐng)輸入借出日期：" << endl;
                cout << "請(qǐng)輸入借出年份：";cin >> (r->reader[i]).bro.m_nYear;
                cout << "請(qǐng)輸入借出月份：";cin >> (r->reader[i]).bro.m_nMonth;
                cout << "請(qǐng)輸入借出日：";cin >> (r->reader[i]).bro.m_nDay;
                cout << "請(qǐng)輸入歸還日期：" << endl;
                cout << "請(qǐng)輸入歸還年份：";cin >> (r->reader[i]).back.m_nYear;
                cout << "請(qǐng)輸入歸還月份：";cin >> (r->reader[i]).back.m_nMonth;
                cout << "請(qǐng)輸入歸還日：";cin >> (r->reader[i]).back.m_nDay;
                r->m_nMoreNum--;
                cout << endl << "成功接到這本書" << endl;
            }
        }
    }
}

9、圖書歸還

根據(jù)輸入的圖書編號(hào)歸還圖書。文章來(lái)源地址http://www.zghlxwxcb.cn/news/detail-492713.html

void TurnBack_TheBook(Info *bth){
