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.

Alarm Clock in C Steps on How to Create a Project
Time needed: 5 minutes
The following is a step-by-step guide that will teach you how to make an alarm clock using C and its source code.
- Step 1: Create a new project.
First open the code blocks IDE and click “create a new project“.
- Step 2: Choose console application.
Next, click the “console application” and after that click “next“.
- 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: ");
scanf("%d",&hrs);
system("cls");
printf("Enter Minute: ");
scanf("%d",&mins);
system("cls");
printf("Enter Second: ");
scanf("%d",&seconds);
system("cls");Function that generates a time in the range [hours, minutes, seconds]
system("cls");
printf("TIMER -> %d : %d : %d ",hrs,mins,--seconds);
Sleep(1000);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)
Beep(i,1000);Downloadable Source Code
Summary
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!

Frequently Asked Questions
How does this C / C++ clock or timer project work?
Uses time.h: time(), localtime(), strftime() to format current time. Display in console with sleep/Sleep loop. Foundation for time-utility mini-project.
What compiler do I need to run this C or C++ project?
For C: gcc (GNU Compiler Collection) or MinGW (Windows). For C++: g++. IDE options: Code::Blocks (lightweight, built-in compiler), Dev-C++ (classic Philippine BSIT favorite), Visual Studio Code with C/C++ extension, CLion (paid). To compile from terminal: gcc program.c -o program (for C) or g++ program.cpp -o program (for C++), then run with ./program (Linux/macOS) or program.exe (Windows).
How do I run this C / C++ project?
Open the .c or .cpp file in your IDE (Code::Blocks, Dev-C++, VS Code). Click Build (or press F9), then Run (or press F5). From terminal: navigate to project folder, run gcc/g++ command above, then ./program. If using file storage, make sure the data file (e.g. records.txt) is in the same folder as the executable.
Can I use this C / C++ project for a BSIT capstone or thesis?
C/C++ projects are usually accepted for 1st-2nd year mini-projects or as building blocks. For a full capstone you would typically pair them with a more interactive frontend (e.g. wrap C++ logic with a Java/Python/PHP frontend, or extend to GTK/Qt for a real GUI). Standalone console C++ capstones are accepted by some panels but rare in 2026.
Why am I getting ‘undeclared identifier’ or ‘cannot find header’ errors?
Three common C/C++ issues: (1) Missing #include directive, e.g. #include
Where can I find more C or C++ projects with source code?
Browse the C and C++ Projects hub for the full library. For Java desktop alternatives see Java Projects. For higher-level languages see Python Projects. For BSIT capstone idea lists see 150 Best Capstone Project Ideas.
