下面的C代码是不工作

Question

我不明白为什么它是只服用第一输入

代码为： -

#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); 
} 

它是只取第一输入，则无需等待用户输入显示的一切。你可以看到下面

试试这个：

#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); 
}
