Can you please suggest me any project that will be done for the first time.

We could suggest many project ideas, but they'll be difficult for you to work on. You should start with something very simple. 

Say - 

1. A program to calculate the area of any 2D geometrical figure when proper inputs are provided.

2. Tic-Tac-Toe program in C. If you have knowledge of graphics in C, you might want to try this out. This is a really challenging program but you may try to attempt it.

3. A simple project in C that generates random shapes to resemble English characters and then asks users to identify them. You may base a login system around this concept.

4. Solve any mathematical problems using C-programming language [ series, progressions etc. ]

You can see many such project ideas on https://www.crazyengineers.com/threads/innovative-and-creative-mini-project-in-c-programming-language.3439/

Once you build your skill level and are comfortable with C Programming, you can take up more complex projects.

Does this help?

Yes. I will do the projects that you suggested. It will help me to get involved into projects for the first time.Later I will improve the complexity of the project.Thank you.
