c++课程设计图书管理系统

以下是一个简单的C++图书管理系统的示例：

#include <iostream>
#include <string>
using namespace std;

struct Book {
    string name;
    double price;
    int number;
};

struct ArrayBooks {
    Book* book;
    int length;
};

// 显示图书信息
void showBooks(ArrayBooks* abs) {
    if (abs->length == 0) {
        cout << "书架为空" << endl;
    } else {
        for (int i = 0; i < abs->length; ++i) {
            cout << "书籍名字 ： " << abs->book[i].name << "\t";
            cout << "书籍价格 ： " << abs->book[i].price << "\t";
            cout << "书籍编号 ： " << abs->book[i].number << endl;
        }
    }
}

// 判断书籍是否存在
int isExist(ArrayBooks* abs, string name) {
    for (int i = 0; i < abs->length; ++i) {
        if (abs->book[i].name == name) {
            return i;
        }
    }
    return -1;
}

// 查找书籍
void checkBook(ArrayBooks* abs) {
    cout << "输入你要查找的书籍" << endl;
    string name;
    cin >> name;
    int ret = isExist(abs, name);
    if (ret != -1) {
        cout << "书名为：" << abs->book[ret].name << "\t";
        cout << "书价格为：" << abs->book[ret].price << "\t";
        cout << "书编号为：" << abs->book[ret].number << endl;
    } else {
        cout << "查无此书" << endl;
    }
}

int main() {
    ArrayBooks abs;
    abs.length = 0;
    abs.book = new Book[100];

    // 添加书籍
    abs.book[abs.length].name = "书籍1";
    abs.book[abs.length].price = 10.99;
    abs.book[abs.length].number = 1;
    abs.length++;

    abs.book[abs.length].name = "书籍2";
    abs.book[abs.length].price = 19.99;
    abs.book[abs.length].number = 2;
    abs.length++;

    // 显示图书信息
    showBooks(&abs);

    // 查找书籍
    checkBook(&abs);

    delete[] abs.book;
    return 0;
}
