圖書管理系統編程

❶ 用C語言編寫一個簡單的圖書管理小程序

源代碼如下：

#include<iostream>

#include<iomanip>

#include<string>

#include<fstream>

#include<stdio.h>

using namespace std;

const int maxb=10000; //最多的圖書

class book//圖書類

{

int tag; //刪除標記1:已刪0:未刪

int number; //isbn書號

char name[20]; //書名

char author[10]; //主編

char number2[10];//版次

char position[20];//出版社

char time[20];//出版年

void addbook(int n,char *na,char *au,char *n2,char *da,char *ti,int pr) //增加圖書
{

tag=0;

number=n;

price=pr;

strcpy(name,na);

strcpy(author,au);

strcpy(number2,n2);

strcpy(position,da);

strcpy(time,ti);

onshelf=1;

}

(1)圖書管理系統編程擴展閱讀

1、源程序中，很多符號都是成對匹配出現的，為避免遺漏必須配對使用的符號。

2、用花括弧括起來的部分，但從程序結構清晰，便於閱讀、理解、維護的角度出發，建議在書寫程序時應遵循以下規則，以養成良好的編程習慣。

3、一個說明或一條語句佔一行，與該結構開始處的左花括弧對齊。

❷ java使用面向對象編程思維編寫圖書管理系統:增加,查詢,修改,刪除,退出，怎麼寫

package com.bms;

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

// book對象
public class Book {
private String bId; // 編號
private String bName; // 書名

// getset方法

public String getbId() {
return bId;
}

public void setbId(String bId) {
this.bId = bId;
}

public String getbName() {
return bName;
}

public void setbName(String bName) {
this.bName = bName;
}

//構造方法
public Book() {
}

public Book(String bId, String bName) {
this.bId = bId;
this.bName = bName;
}

/*
* 增加
* */
public static List<Book> add(List<Book> list) {
Scanner sn = new Scanner(System.in);
System.out.print("請輸入編號:");
String bid = sn.next();
System.out.print("請輸入名稱:");
String bName = sn.next();
Book book = new Book(bid, bName);
for (Book b : list) {
if (b.bId.equals(book.bId)) {
System.out.println("編號重復，請重新輸入！");
return list;
}
}
list.add(book);
System.out.println("添加成功！");
return list;
}

/*
* 查詢
* */
public static void query(List<Book> list) {
System.out.println("編號\t書名");
for (Book b : list) {
System.out.println(b.getbId() + "\t" + b.getbName());
}
}

/*
* 修改
* */
public static void update(List<Book> list) {
query(list);
Scanner sc = new Scanner(System.in); // 鍵盤輸入的對象
System.out.print("請輸入編號:");
String s = sc.next();
Integer id = null;
for (int i = 0; i < list.size(); i++) {
id = list.get(i).getbId().equals(s) ? i : null;
}
if (id == null) {
System.out.println("輸入的編號不存在，請重新選擇！");
return;
}
System.out.print("請輸入新的書名:");
String newName = sc.next();
list.get(id).setbName(newName);
System.out.print("修改成功！");
}

/*
* 刪除
* */
public static void del(List<Book> list) {
query(list);
Scanner sc = new Scanner(System.in); // 鍵盤輸入的對象
System.out.print("請輸入編號:");
String s = sc.next();
for (int i = 0; i < list.size(); i++) {
if (list.get(i).getbId().equals(s)) {
list.remove(i);
return;
}

}
System.out.println("輸入的編號不存在，請重新選擇！");
}

}

/*
* 測試*/
class Test {
public static void main(String[] args) {
List<Book> bookList = new ArrayList<>(); // 存放所有圖書的列表
bookList.add(new Book("1", "Java 基礎")); // 圖書的列表添加一本圖書
System.out.print("歡迎進入圖書管理系統,");
boolean b = true;
while (b) {
System.out.print("請選擇：\n1.增加\n2.查詢\n3.修改\n4.刪除\n5.退出\n(輸入序號):");
Scanner sn = new Scanner(System.in); // 鍵盤輸入的對象
String select = sn.next();
switch (select) {
case "1":
System.out.println("您選擇了增加");

Book.add(bookList);
break;
case "2":
System.out.println("您選擇了查詢:");
Book.query(bookList);
break;
case "3":
System.out.println("您選擇了修改");
Book.update(bookList);
break;
case "4":
System.out.println("您選擇了刪除");
Book.del(bookList);
break;
case "5":
System.out.println("您選擇了退出");
b = false;
System.out.println("退出程序！");
break;
default:
System.out.println("輸入錯誤的序號，請重新輸入");
break;
}
}

}
}
