This list can be composed in a loop. I will give you the general idea in pseudocode, but you will have to write it in C.

Code:

for each car in inventory:
  if strcmp(car.make, userMake) == 0:
    copy car to filtered list

It's not the fanciest way, but it works. Once you have that list you can pare it down even further with the user's other specifications by using similar techniques. Or just print out the filtered list with printf().

This is for Auto Dealership to keep track of what cars they have in stock, not for user purchase.The user is AUTO DEALERSHIP!!

I see. In that case, absolutely nothing about my suggestion changes. An auto dealership purchases cars from automobile factories. That's all what you're concerned about really means.

Hi guys, Since my last visit here,I have made few changes in the code,implemented a tree to give users choice,seperated some codes into method and then into different files.I am now running the main program from main method file.The program works well but isn't fully functional.I was looking to display the content of my inventory into a text file from which I plan to use a sorting file to sort the contents.The thing is the method works well but only for one line and console crashes if I try to rerun the method.Also,I don't know how should I sort the contents from text file(What data structure?)
Edit(After rewriting code into write_text method)

Code:

void write_text(){
	
		struct node *ptr=start;
		int j;
		FILE *ptr_file;
		ptr_file =fopen("output.txt", "w");
		while(ptr != NULL){
			fprintf(ptr_file,"\n%d.\t%s   %s   %d   %s   \n", j,ptr->data.carname,ptr->data.carmodel,ptr->data.caryear,ptr->data.cartype);
			ptr = ptr->next;
			j++;
		}
		fclose(ptr_file);
	
}

The functions starting with f doesn't work in display method for saving linked list contents to file.

Can you please help me with this??
