المكتبه الالكترونيه

السلام عليكم

تحيه للمبرمجين واتمنى منكم مساعدتي في هذا البرنامج

2. A data file contains information on all books checked out from a college library. Each record of the data file consists of the following fields:

1. Id number of borrowers (string)

2. Call number of book (string)

3. Name of author (structure)

4. Title of book (string)

5. Due date (mm/dd/yy) (string)

Write a program that declares a structure to store the information, reads the data for each book, and prints a list of all books checked out. Your program should include separate functions for reading and writing.

3. Update program 1 for it to be a menu driven program, display the following menu:

Electronic Library

1. Add a book

2. Search by author

3. Search by title

4. Search by due month

5. Quit

Enter your choice:

Add functions to perform each of the previous menu options.

وهذي محاولتي لكني توقفت عن عملية البحث في functions

char first[80];

};

char date[80];

}book;

int addbook();

void author();

void title();

void duemonth();

void print(int);

int main()

{

int choice,exit=0,result;

book temp[80];

system("cls");

while(!exit){

printf("1 to add book\n");

printf("2 to search by author\n");

printf("3 to search by title\n");

printf("4 to search by due month\n");

رجاء خاص ليت كل من يعرف يساعدني

بليييييييييييييييييز
