# C Program to Implement Student Database using Structure

This program is written using DEV C++ version 5. You can use any other standard C compiler to compile and run this program.

The best way to learn programming is to do lot of practice writing programs and understanding the logic behind achieving the solution to the problems. In this way you can easily master the programming skills.

### AIM

To write a program in C that implement Student database using Structures.
