Simple Attendance System

A simple Command Line Interface (CLI) attendance system written in C++

---

Overview

This project is a simple attendance management system built using C++.
It runs in a terminal (CLI) environment and allows users to:

• Record student attendance using a student ID (NIM)
• Prevent duplicate attendance entries
• Cancel or remove attendance records
• Display attendance data along with timestamps

The system is designed for learning purposes and demonstrates the use of arrays, structures, functions, and basic input validation in C++.

Platform Compatibility

This repository contains two source files with the same system logic but different implementations for the delay function (Sleep), depending on the operating system.

Files

• main-windows.cpp
  Uses Sleep() from the <windows.h> library.

• main-linux.cpp
  Uses std::this_thread::sleep_for(std::chrono::milliseconds(ms)) from the C++ standard library.

Aside from the delay implementation, both files are functionally identical.

Features

• CLI-based interactive menu
• Attendance recording based on valid student data
• Duplicate attendance prevention
• Attendance cancellation with confirmation
• Automatic timestamp generation
• Simple and structured program flow

Program Structure

The system is divided into several logical parts:

• Data Structures
  • AttendanceCreate for valid student data
  • AttendanceEntry for attendance rec

How to Compile and Run

Note

Make sure you are using a compiler that supports C++11 or newer.

Windows

g++ main-windows.cpp -o attendance.exe && ./attendance.exe

Linux

g++ main-linux.cpp -o attendance && ./attendance
