Structure related program for C Language
Code for accessing structure and creating a marksheet like project. This code is for creating and accessing structure with an example using C Language.
This is the best and easy code for learning Structure and it’s use. Here each and every functions are used using most simple logic and structure.
After understanding this code you will be able to write any structure related program easily.
