结构作为函数参数：void printBook( struct Books book )
C语言结构体完整解析（四）：使用函数strcpy()可直接调用结构体成员并赋值
#include <stdio.h> #include <string.h> struct Books { char title[50]; char author[50]; char subject[100]; int book_id; }; /* 函数声明 */ void printBook( struct Books book ); int main( ) { struct Books Book1; /* 声明 Book1，类型为 Books */ struct Books Book2; /* 声明 Book2，类型为 Books */ /* Book1 详述 */ strcpy( Book1.title, "C Programming"); strcpy( Book1.author, "Nuha Ali"); strcpy( Book1.subject, "C Programming Tutorial"); Book1.book_id = 6495407; /* Book2 详述 */ strcpy( Book2.title, "Telecom Billing"); strcpy( Book2.author, "Zara Ali"); strcpy( Book2.subject, "Telecom Billing Tutorial"); Book2.book_id = 6495700; /* 输出 Book1 信息 */ printBook( Book1 ); /* 输出 Book2 信息 */ printBook( Book2 ); return 0; } void printBook( struct Books book ) { printf( "Book title : %s\n", book.title); printf( "Book author : %s\n", book.author); printf( "Book subject : %s\n", book.subject); printf( "Book book_id : %d\n", book.book_id); }
