修改以下代码的输出格式保持整齐与美观：void viewAllBooks char bookID20; for int i = 0; i numBooks; i++ printf查询结果：n; printf编号：sn booksibookID; printf书名：sn booksibookName;

void viewAllBooks() { char bookID[20]; for (int i = 0; i < numBooks; i++) { printf("查询结果：\n"); printf("编号：%s\n", books[i].bookID); printf("书名：%s\n", books[i].bookName); printf("作者：%s\n", books[i].author); printf("数量：%d\n", books[i].amount); printf("出版社：%s\n\n", books[i].pub); while (i == numBooks) { return; } } }
