c语言程序设计课设图书管理系统

根据提供的引用内容，C语言程序设计课设的图书管理系统主要包括以下功能：图书的录入、删除、查找和导入/导出等。图书的属性包括书号、书名、第一作者、版次、出版社、出版年等信息。

以下是一个简单的C语言程序设计课设图书管理系统的示例：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#define MAX_BOOKS 100

struct Book {
    char bookId[20];
    char title[100];
    char author[100];
    int edition;
    char publisher[100];
    int year;
};

struct Book books[MAX_BOOKS];
int numBooks = 0;

void addBook() {
    if (numBooks >= MAX_BOOKS) {
        printf("图书库已满，无法添加新书。\n");
        return;
    }

    struct Book newBook;
    printf("请输入书号：");
    scanf("%s", newBook.bookId);
    printf("请输入书名：");
    scanf("%s", newBook.title);
    printf("请输入第一作者：");
    scanf("%s", newBook.author);
    printf("请输入版次：");
    scanf("%d", &newBook.edition);
    printf("请输入出版社：");
    scanf("%s", newBook.publisher);
    printf("请输入出版年：");
    scanf("%d", &newBook.year);

    books[numBooks] = newBook;
    numBooks++;

    printf("图书添加成功。\n");
}

void deleteBook() {
    char bookId[20];
    printf("请输入要删除的书号：");
    scanf("%s", bookId);

    int found = 0;
    for (int i = 0; i < numBooks; i++) {
        if (strcmp(books[i].bookId, bookId) == 0) {
            for (int j = i; j < numBooks - 1; j++) {
                books[j] = books[j + 1];
            }
            numBooks--;
            found = 1;
            break;
        }
    }

    if (found) {
        printf("图书删除成功。\n");
    } else {
        printf("未找到该书号的图书。\n");
    }
}

void searchBook() {
    char bookId[20];
    printf("请输入要查找的书号：");    scanf("%s", bookId);

    int found = 0;
    for (int i = 0; i < numBooks; i++) {
        if (strcmp(books[i].bookId, bookId) == 0) {
            printf("书号：%s\n", books[i].bookId);
            printf("书名：%s\n", books[i].title);
            printf("第一作者：%s\n", books[i].author);
            printf("版次：%d\n", books[i].edition);
            printf("出版社：%s\n", books[i].publisher);
            printf("出版年：%d\n", books[i].year);
            found = 1;
            break;
        }
    }

    if (!found) {
        printf("未找到该书号的图书。\n");
    }
}

void exportBooks() {
    FILE *file = fopen("books.txt", "w");
    if (file == NULL) {
        printf("无法打开文件。\n");
        return;
    }

    for (int i = 0; i < numBooks; i++) {
        fprintf(file, "%s,%s,%s,%d,%s,%d\n", books[i].bookId, books[i].title, books[i].author, books[i].edition, books[i].publisher, books[i].year);
    }

    fclose(file);

    printf("图书导出成功。\n");
}

void importBooks() {
    FILE *file = fopen("books.txt", "r");
    if (file == NULL) {
        printf("无法打开文件。\n");
        return;
    }

    numBooks = 0;
    while (fscanf(file, "%[^,],%[^,],%[^,],%d,%[^,],%d\n", books[numBooks].bookId, books[numBooks].title, books[numBooks].author, &books[numBooks].edition, books[numBooks].publisher, &books[numBooks].year) != EOF) {
        numBooks++;
    }

    fclose(file);

    printf("图书导入成功。\n");
}

int main() {
    int choice;

    do {
        printf("图书管理系统\n");
        printf("1. 添加图书\n");
        printf("2. 删除图书\n");
        printf("3. 查找图书\n");
        printf("4. 导出图书\n");
        printf("5. 导入图书\n");
        printf("0. 退出\n");
        printf("请选择操作：");
        scanf("%d", &choice);

        switch (choice) {
            case 1:
                addBook();
                break;
            case 2:
                deleteBook();
                break;
            case 3:
                searchBook();
                break;
            case 4:
                exportBooks();
                break;
            case 5:
                importBooks();
                break;
            case 0:
                printf("感谢使用图书管理系统，再见！\n");
                break;
            default:
                printf("无效的选择，请重新输入。\n");
                break;
        }
    } while (choice != 0);

    return 0;
}

这个示例实现了图书管理系统的基本功能，包括添加图书、删除图书、查找图书、导入图书和导出图书等操作。你可以根据需要进行修改和完善。
