Digital Clock
Description This C program is a digital clock that continuously displays the current date and time. The clock can be set to either a 24-hour or 12-hour format based on the user's preference. It uses system time to update the display every second, providing an accurate and real-time digital clock.
Features:
- Time Format Selection Users can choose between a 24-hour format or a 12-hour format. The program prompts the user to select the preferred time format at the start.
- Real-Time Display Continuously updates and displays the current date and time. The date is displayed in the format: "Day of the week Month Day Year" (e.g., "Monday July 13 2024"). The time is displayed according to the selected format: "HH:MM " for 24-hour or "HH:MM AM/PM" for 12-hour.
- Cross-Platform Compatibility Clears the screen before each update to provide a clean display. Compatible with both Windows and Unix-like systems.
Key Functions: fill_date(char* buffer): Fills the buffer with the current date in the specified format. fill_time(char* buffer, int format): Fills the buffer with the current time in the specified format (24-hour or 12-hour). input_format(): Prompts the user to select the time format and returns the choice. clear_screen(): Clears the console screen for both Windows and Unix-like systems to update the display.
Get Started To use this digital clock, compile and run the provided source code. Follow the on-screen prompts to select the desired time format.
Compilation Instructions Save the source code to a file named digital_clock.c. Open a terminal or command prompt. Navigate to the directory where the source code file is saved. Compile the code using a C compiler, e.g., gcc digital_clock.c -o digital_clock. Run the executable, e.g., ./digital_clock on Unix-like systems or digital_clock.exe on Windows.
Conclusion This project demonstrates the use of system time functions and cross-platform compatibility in C programming. It showcases my ability to create a real-time application with user interaction and continuous updates. The digital clock can be extended with additional features such as alarm functionality or customization options for the display.
