Real-Time Clock Display in C++

Overview

This is a simple C++ program that continuously displays the current local time in HH:MM:SS format. The time updates every second, clearing the console screen before each update.

Features

• Fetches the current system time.
• Displays the time in real-time with automatic updates.
• Clears the console before each update for a clean display.

Requirements

• A C++ compiler (e.g., g++).
• A Unix-like operating system (Linux/macOS) or Windows with a compatible terminal.

Compilation & Execution

Linux/macOS:

1. Open a terminal and navigate to the directory containing the source file.
2. Compile the program using:

   g++ -o clock clock.cpp

3. Run the program:

   ./clock

Windows (Using MinGW):

1. Open a terminal and navigate to the source file location.
2. Compile the program:

   g++ -o clock.exe clock.cpp

3. Run the program:

   clock.exe

How It Works

1. The program enters an infinite loop.
2. It retrieves the current system time using time(0) and localtime().
3. It clears the console using �[H�[J (ANSI escape sequence).
4. The formatted time is printed in HH:MM:SS format.
5. The program waits for 1 second using sleep(1), then repeats.

Notes

• The program uses �[H�[J to clear the console, which works in Unix-like terminals. On Windows, use system("cls") instead.
• To stop the program, press Ctrl + C.
