Used libraries:

#include <stdio.h>
#include <stdlib.h> 
#include <unistd.h>
#include <string.h>
#include <ctype.h>
#include <stdbool.h>

Where to start

The main() function serves as the entry point for the program. It continuously reads user input, processes various commands, and manages a linked list database of nations and their respective medal counts.

Allowed Commands Description:

• Add Nation (A): Add a country to the database.
  A <name>
• Write to File (W): Saves the current database to a file.
  W <filename>
• Add Medals (M): Updates a nation's medal counts.
  M <name> <gold> <silver> <bronze>
• Print Sorted Database (L): Sorts and displays the database contents.
  L
• Load from File (O): Loads a database from a file, replacing the current one.
  O <filename>
• Quit command (Q): Exit the program.
  Q

Example:

A Finland
>> SUCCESS
W db.txt
>> SUCCESS
M Finland 1 2 3
>> SUCCESS
L
>> Finland 1 2 3
>> SUCCESS
O db.txt
>> SUCCESS
Q
>> exit program

Skills

• Basic concepts of systems-level programming.
• Basics of the C programming language.
• Dynamic memory management and its application in common data structures.
