Alarm Clock Project

Overview

This project is a simple alarm clock program written in C. It allows users to set, cancel, and monitor alarms based on a 12-hour format with AM/PM notation. The program provides a text-based menu interface for interacting with the alarm system and an ongoing loop to check and activate alarms as needed.

Features

• Set Alarms: Configure alarms with a specific hour, minute, second, and AM/PM period.
• Cancel Alarms: Remove alarms from the active list.
• View Alarms: Display all currently set alarms.
• Monitor Alarms: Continuously check and trigger alarms at their scheduled times.
• User Interface: Simple menu-driven interface for ease of use.

Prerequisites

• A C compiler (e.g., GCC)
• Basic understanding of how to compile and run C programs

Installation

1. Clone the Repository: Download the source code from the repository.

   git clone https://github.com/mdriyadkhan585/alarm-clock-C
   cd alarm-clock-C 

2. Compile the Program: Use a C compiler to compile the source code. For GCC, you can use:

   gcc -o alarm_clock alarm_clock.c

3. Run the Program: Execute the compiled program:

   ./alarm_clock

Usage

Main Menu

Upon running the program, you will be presented with the main menu. Here are the available options:

1. Set Alarm: Configure a new alarm.

   • Hour (1-12): Enter the hour in 12-hour format.
   • Minute (0-59): Enter the minute.
   • Second (0-59): Enter the second.
   • AM/PM (A/P): Specify AM or PM.

   Example:

   Enter alarm time (12-hour format):
   Hour (1-12): 7
   Minute (30): 15
   Second (0): 0
   AM/PM (A/P): A
   

2. Cancel Alarm: Remove an existing alarm.

   • View the list of active alarms.
   • Enter the number of the alarm you wish to cancel.

   Example:

   Enter the number of the alarm to cancel: 1
   

3. Show Alarms: Display all currently set alarms.

   • A list of all active alarms will be shown with their respective times.

4. Done: Finalize alarm setup and start the monitoring process.

   • When you choose "Done", the program will exit the menu and start monitoring for active alarms.

Program Operation

• Alarm Monitoring: After choosing "Done", the program enters an ongoing loop where it continuously checks the current time against the set alarms.
• Alarm Activation: When the system time matches the time of an active alarm, the alarm will trigger, and a message will be displayed.
• Alarm Deactivation: Once triggered, the alarm will be deactivated automatically to prevent multiple triggers.

Troubleshooting

• Invalid Input: If you enter invalid data (e.g., an hour outside 1-12), the program will prompt you to enter valid values.
• Program Not Starting: Ensure you have compiled the program correctly and have the necessary permissions to execute it.
