Simple Book Loan System

How to code a simple Book Loan System Using :

• The book must be returned within a maximum loan period of 10 days.
• Fines are imposed on overdue items at the rate of 0.50 per book per day.
• Define constants for loan period and fine rate.
• Read the number of books and the number of days.
• Calculate and display number of days overdue and total fine.

#include <stdio.h> #include <stdlib.h> #define MAX_LOAN_PERIOD 10 #define FINE_RATE 0.50 int main() { int booksCount, daysCount, daysOverdue; double fine; printf("----------------\n" "BOOK LOAN SYSTEM\n" "----------------\n"); printf("Number of books : "); scanf("%d", &booksCount); printf("The days of loan : "); scanf("%d", &daysCount); daysOverdue = daysCount - MAX_LOAN_PERIOD; fine = booksCount * daysOverdue * FINE_RATE; printf("------------------------------\n"); printf("Days Overdue : %d\n", daysOverdue); printf("Fine : %.2f\n\n", fine); system("pause"); return 0; }
