Alarm Clock Program in C with Source Code

The Alarm Clock project that was written in C was developed as a simple console application. There will be a clock that appears, and it will display the current time in hours, minutes, and seconds. Using the time picker, the user should be able to select all three of the following fields: hours, minutes, and seconds.

Each field will have an up button and a down button so that the value can be set. The range for the hour field is 0 to 23, the range for the minutes field is 0 to 59, and the range for the seconds field is 0 to 59.

This Alarm Clock is written in C Framework, and it also comes with a free download of the source code. To get the source code, simply locate it below and click the “download now” button.

  • Step 3: Choose C language.

    Then , choose “C language” and click “next“.

  • Step 4: Name your project.

    Lastly, name the project you’ve created and click “next” after that click “finish“.

  • Step 5: The actual code.

    Finally, we will now start adding functionality to our C Framework by adding some functional codes.

Functionality and Codes of the Alarm Clock in C with Source Cod

Before we can manipulate inputs and outputs, we must first add the stdio library and add the following code in your main.c

#include <stdio.h>
#include <stdlib.h>

Function on how to create a mean menu in quiz game.

int main()
    int hrs, mins, seconds,i=0;
    printf("Enter Hours: ");
    printf("Enter Minute: ");
    printf("Enter Second: ");

Function that generates a time in the range [hours, minutes, seconds]

        printf("TIMER -> %d : %d : %d ",hrs,mins,--seconds);

In this section, we will learn on how create a for loop. To start with, add the following code in your main.c

for ( i = 100; ; i = i + 5)

Downloadable Source Code


In conclusion, this Alarm Clock in C with Source Code can be helpful to students as well as professionals who are interested in learning the C Programming Language. This project can also be tailored to meet the specific needs of the individual participant. I really hope that working on this project helps you improve your skills. Happy Coding!
