STRUCT Library System
I badly need to finish this program before wednesday nextweek :(
i am only a freshmen college student and i am still getting familiar of all the codes in c++. My only problem in this code is how to put a BORROWING and RETURNING process. I wanted to have a process like this:
1. After the user chooses BORROW, the program will ask for the ID No. of the student.
2. If the student ID No. is available, the program will display its info and ask if the user would like to borrow a book.
3. If the user chooses yes, the program will display the categories of books such as filipiniana etc.
4. Then the user will choose which kind of book.
5. After borrowing the program will display that the borrowing was successful.
The returning process goes the same way..
THANK YOU SO MUCH.
Here's my code:
#include<iostream>
#include<string>
#include<iomanip>
#include<stdio.h>
#include<conio.h>
using namespace std;
