Singly Linked List OpenGL Computer Graphics Program

C is a simple and easy language, general-purpose, imperative computer programming language. C Programming is vast with so many concept behind it (operators, loops, functions, single and double dimensional arrays, performing operations on strings, files, pointers etc.). One of the key concept which we are going to learn in this post is about Linked List.

Linked list in c the concept which not many of us grab properly. It is very important programming concept in C. There are many Operation in the Linked list, before going to learn about them, I want to tell you we are not giving concept of Linked list in c, but Computer Graphics Program.  Yes we are using the C language as the primary language to write the programm but here we deal with graphics programming and not c programming. You must know about the Linked List in C which is pre-assumed here.  The program uses the OpenGL API to render graphics. Hence it is basically a C or C++ Computer Graphics Program using OpenGL.

Some basic details about Singly Linked List - 

Definition : A Linked list or List is a sequence of data structures (sequence of data linked with each other), which are connected together via links.

Singly linked list is a sequence of items/data/ in which  the items are link to its next element in the sequence. In Singly linked list the item or elements individually called as node. Each node have two parts - Data and Link.

Data(info) − Each Node of a linked list contain or store some data/info. This part of node contain the actual value.
Link − Each link of a linked list contains a link(address) to the next link.

Various operations on Singly Linked list in C

Singly Linked list is a linear data structure with many operations can be done on the nodes unlike the array in C. Various operations that can be done are listed below -
  1. Creation
  2. Insert at starting
  3. Insert at position(user's choice)
  4. Insert at end
  5. Delete 1st node
  6. Delete last node
  7. Delete at position(user's choice)
  8. Display 
The source code of the C program to illustrate the operations of singly linked list. Try to learn it first in C then go for graphics program.

Singly Linked List OpenGL Computer Graphics Program

This Computer Graphics Program is operated via two windows as seen in the image. With one we insert the data while graphics is shown in other window. There is some problem in the programm so we need to keep patience in input the data to program. Everything is working perfect if done calmly, while in some PC with less graphics, it may stop working.
