图书管理系统编程

❶ 用C语言编写一个简单的图书管理小程序

源代码如下：

#include<iostream>

#include<iomanip>

#include<string>

#include<fstream>

#include<stdio.h>

using namespace std;

const int maxb=10000; //最多的图书

class book//图书类

{

int tag; //删除标记1:已删0:未删

int number; //isbn书号

char name[20]; //书名

char author[10]; //主编

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) //增加图书
{

tag=0;

number=n;

price=pr;

strcpy(name,na);

strcpy(author,au);

strcpy(number2,n2);

strcpy(position,da);

strcpy(time,ti);

onshelf=1;

}

(1)图书管理系统编程扩展阅读

1、源程序中，很多符号都是成对匹配出现的，为避免遗漏必须配对使用的符号。

2、用花括号括起来的部分，但从程序结构清晰，便于阅读、理解、维护的角度出发，建议在书写程序时应遵循以下规则，以养成良好的编程习惯。

3、一个说明或一条语句占一行，与该结构开始处的左花括号对齐。

❷ java使用面向对象编程思维编写图书管理系统:增加,查询,修改,删除,退出，怎么写

package com.bms;

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

// book对象
public class Book {
private String bId; // 编号
private String bName; // 书名

// 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;
}

//构造方法
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("请输入编号:");
String bid = sn.next();
System.out.print("请输入名称:");
String bName = sn.next();
Book book = new Book(bid, bName);
for (Book b : list) {
if (b.bId.equals(book.bId)) {
System.out.println("编号重复，请重新输入！");
return list;
}
}
list.add(book);
System.out.println("添加成功！");
return list;
}

/*
* 查询
* */
public static void query(List<Book> list) {
System.out.println("编号\t书名");
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); // 键盘输入的对象
System.out.print("请输入编号:");
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("输入的编号不存在，请重新选择！");
return;
}
System.out.print("请输入新的书名:");
String newName = sc.next();
list.get(id).setbName(newName);
System.out.print("修改成功！");
}

/*
* 删除
* */
public static void del(List<Book> list) {
query(list);
Scanner sc = new Scanner(System.in); // 键盘输入的对象
System.out.print("请输入编号:");
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("输入的编号不存在，请重新选择！");
}

}

/*
* 测试*/
class Test {
public static void main(String[] args) {
List<Book> bookList = new ArrayList<>(); // 存放所有图书的列表
bookList.add(new Book("1", "Java 基础")); // 图书的列表添加一本图书
System.out.print("欢迎进入图书管理系统,");
boolean b = true;
while (b) {
System.out.print("请选择：\n1.增加\n2.查询\n3.修改\n4.删除\n5.退出\n(输入序号):");
Scanner sn = new Scanner(System.in); // 键盘输入的对象
String select = sn.next();
switch (select) {
case "1":
System.out.println("您选择了增加");

Book.add(bookList);
break;
case "2":
System.out.println("您选择了查询:");
Book.query(bookList);
break;
case "3":
System.out.println("您选择了修改");
Book.update(bookList);
break;
case "4":
System.out.println("您选择了删除");
Book.del(bookList);
break;
case "5":
System.out.println("您选择了退出");
b = false;
System.out.println("退出程序！");
break;
default:
System.out.println("输入错误的序号，请重新输入");
break;
}
}

}
}
