以下C代碼不起作用

Question

我不明白為什么只接受第一次輸入

代碼是：-

#include <stdio.h>

typedef struct _book
{
    char title[100];
    char author[50];
    char genre[30];
}
books;


// function to get title from user
void get_title(books *b)
{
    printf("Enter the title of the book: ");
    scanf("%[^\n]", b->title);
}

// function to get author from user
void get_author(books *b)
{
    printf("Enter name of the author: ");
    scanf("%[^\n]", b->author);
}

// function to get genre from user
void get_genre(books *b)
{
    printf("Enter the genre of the book: ");
    scanf("%[^\n]", b->genre);
}

// function to display book title
void print_title(books b)
{
    printf("Title of the book is: %s\n", b.title);
}

// function to display book author
void print_author(books b)
{
    printf("Author of the book is: %s\n", b.author);
}

// function to display book genre
void print_genre(books b)
{
    printf("Genre of the book is: %s\n", b.genre);
}


int main()
{
    // defining book variable
    books book;

    // getting inputs from user
    get_title(&book);
    get_author(&book);
    get_genre(&book);


    // displaying outputs
    printf("Details of the book :-\n");
    print_title(book);
    print_author(book);
    print_genre(book);
}

它僅接受第一個輸入，然后顯示所有內容，而無需等待用戶輸入。 您可以在下面給出的鏈接中看到輸出圖像

在這里您可以看到輸出：-

嘗試這個 ：

#include <stdio.h>

typedef struct _book
{
    char title[100];
    char author[50];
    char genre[30];
}
books;


// function to get title from user
void get_title(books *b)
{
    printf("Enter the title of the book: ");
    scanf(" %[^\n]", b->title);
}

// function to get author from user
void get_author(books *b)
{
    printf("Enter name of the author: ");
    scanf(" %[^\n]", b->author);
}

// function to get genre from user
void get_genre(books *b)
{
    printf("Enter the genre of the book: ");
    scanf(" %[^\n]", b->genre);
}

// function to display book title
void print_title(books b)
{
    printf("Title of the book is: %s\n", b.title);
}

// function to display book author
void print_author(books b)
{
    printf("Author of the book is: %s\n", b.author);
}

// function to display book genre
void print_genre(books b)
{
    printf("Genre of the book is: %s\n", b.genre);
}


int main()
{
    // defining book variable
    books book;

    // getting inputs from user
    get_title(&book);
    get_author(&book);
    get_genre(&book);


    // displaying outputs
    printf("Details of the book :-\n");
    print_title(book);
    print_author(book);
    print_genre(book);
}
