C
include<stdio.h> struct book; { char Name[30]; char Authors[30] ; int ISBN code[30]; float Price; } int main() { struct book b; printf(" Enter the book name:"); fgets(b.book_name, 30, stdin); printf("Enter the author name:\n"); fgets(b.author, 30, stdin); printf("Enter the ISBN code\n:"); scanf("%d", &b.book_code); printf("Enter the Price:"); scanf("%f", &b.Price); printf("The Details of the book is:\n\n"); printf("Book name is:\n"); printf("Author name is:\n"); printf("ISBN code is:%d\n", b.book_code); printf("book Price is: %0.2f\n", b.Price); return 0; }
私が試したこと:
‘b’ のストレージ サイズが不明です
ブック b を構造化します。
「{」トークンの前に識別子または「(」が必要です
{
^
解決策 1
私はすでにあなたに言った: C
その構文へのカジュアルなアプローチは好きではありません。正確でなければなりません。 試す:
C
#include <stdio.h> struct book { char Name[30]; char Author[30] ; char Isbn[30]; float Price; }; int main() { struct book b; printf(" Enter the book name:"); fgets(b.Name, 30, stdin); printf("Enter the author name:\n"); fgets(b.Author, 30, stdin); printf("Enter the ISBN code\n:"); fgets(b.Isbn, 30, stdin); printf("Enter the Price:"); scanf("%f", &b.Price); printf("The Details of the book is:\n\n"); printf("Book name is %s:", b.Name); printf("Author name is:%s", b.Author); printf("ISBN code is:%s", b.Isbn); printf("book Price is: %0.2f\n", b.Price); return 0; }
解決策 2
これはあなたの前の質問に対する 2 回目の試みであり、まだいくつかの非常に基本的なエラーがあります。
C++
#include<stdio.h> // include statements must start with the '#' character struct book // do not put a semi-colon on this line { char Name[30]; char Authors[30] ; int ISBNcode[30]; // ISBN and code need to be one word. And are you sure you want an array of int types? float Price; }; // do put a semi-colon on this line int main() { struct book b; printf(" Enter the book name:"); fgets(b.book_name, 30, stdin); // in this and the following lines you are not using the correct field names printf("Enter the author name:\n"); fgets(b.author, 30, stdin); printf("Enter the ISBN code\n:"); scanf("%d", &b.book_code); // this is not valid as ISBNcode is an array printf("Enter the Price:"); scanf("%f", &b.Price); printf("The Details of the book is:\n\n"); // printf("Book name is:\n"); // these statements are incomplete printf("Author name is:\n"); // printf("ISBN code is:%d\n", b.book_code); printf("book Price is: %0.2f\n", b.Price); return 0; }
