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

I  haven't done a single project. I want to start doing projects in c and python.

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.
