[Solved]Need Help Completing C Program Program Include Loop Allow User Repeat Program Program Must Q37122207
Need help with completing this C program. Program will include aloop and allow the user to repeat the program. Program must includepointer notation, fgets and lists.
Sequence of options:
-Populate existing trucks …this is done once as existing trucksare given (see populate trucks function)
-start loop, display menu (switch case must be used)
-code the necessary option based on user choice:
—if choice is 1, call the addTruck function, validate all inputaccordingly, then call the generate miles(see add truckfunction
remember that you need to save all trucks in a listand not an array of objects
—if choice is 2, prompt for a truck ID, search for it and iffound display all info about the truck and if the truck is to beauctioned or not
must be displayed based on the status
remeber that you need to process your search using the list
—if choice is 3, display all trucks that are to be auctioned, inthis case, check the status of the truck and if true, display thegiven truck
—if choice is 4, quit program with the right message.
IMPORTANT! WHEN USER DECIDES TO QUIT WRITE ALL RECORDS FROM THELIST TO DISK AND THEN READ THEM BACK INTO A NEW LIST FORVALIDATION
These are the functions I have so far (they program is notworking properly)

“===>Enter choice: “);
scanf(“%d”, &choice);
return choice;
