“this a first year project in computer science in programming for “c””
I just want to tell you this a c program , i’m actually trying  my best to get the same code the same as the output, as i am currently struggling , as you can see i already started  the program , we are only allowed to use quicksort algorithm and we have to read the input from file  , all i have to do is to do is the anagrams and  the missing anagrams, and i  kinda need help to do it , as you can see from my program the “duck” word is missing after it get sorted and i don’t why , anyway all i want is to have a code that is read through the input file by using quicksort algorithm, anagrams and finally missing anagrams

the same as it looks like in the the “output.txt” file
thanks
