Project 1 - Creation of user defined data type to implement the user interfaces for working with ‘Set’ (Mathematical Set theory) using Linked List

Implementation of interface for mathematical Set Theory using C programming.

First, we are creating the structure as a typedef model to rename the user-defined name.

In that, we are creating two data types int for storing the integer value, and the pointer variable is used it storing the address of the same structure itself.

And after we are creating the main function we get the values of list 1 and list 2 using the for loop and using the many function call in that.

And then we are creating the different functions which are mentioned in the main program.

Creating two lists of data using the linked list method.

First, we are getting the size of the list. Using the for loop we are inserting the data. Inside the foe loop, we use the insert node function.

In these functions, we are using arguments are head address and value from the user.

Inside the inserted node, we are creating the size of the list using the malloc function.

Entering the data in the data area, And storing the address of the head to the next pointer and we are storing the new node address in the head for the next update.

Likewise, we are creating the two lists.

Getting Union of two lists.

Here we get a function call of getting union with the argument of head1 and head2

In the union function, we are using the head unit as a list by inserting the value of the first list in the union and jumping to the next area by addressing stores in the next.

Insert node function as same as the function which is used for the creation of the linked list.

Using another while loop we are getting the second list.

Using the compare function using not we are getting only the value that is not placed in the list one and inserted in the union in the list.

Getting Intersectionthe of two lists.

Inthe the intersection, we are easy to get an intersection because just we compare to list and return the value which is placed in both lists commonly.

Using the If command comparing the data of lists 1 and 2.

if the condition is true it passes the next step which has an intersection list and using the insert function we are inserting the data into that list.

Display function

It is used to display the data of the different lists by using different arguments passing to the display function.

So creating the temporary list with the head is null. And print data and use the next address stored in the pointer variable pointing to the structure.

If head next has it recognize it is last node .
