So what the program should basically do is we input filename -i input.txt -o output.txt -c in the command line (command line arguments (argc and argv)) and the program should read the inputfile, count how many words there are, and if there is -c it should convert all of uppercases to lowercases and ignore punctuation. And then count the occurrences of every word and output the result in the ouput.txt. If there is no -i input.txt it should prompt for input from user and do the same and if there is no -o output.txt it should print the output in the compiler. So what's not working from my program is **if(argc == 4)**, **if(argc == 3)**. I don't have the function for wordOccurrences for now. I know that the header "**count.h**" should't be like a header but for now it works.

So Yeah i would appreciate any help. I am new to C and if you have another idea for how i should make the program work post your ideas. Anything would help really.
