Function in c comments appreciated

8. Write a function that counts the characters and lines in a file. A character can be any character including letter, digit, symbol, blank, tab, newline, etc. A line is a sequence of characters terminated by newline character or end of file character. The function prototype is void file count (char file, int *characters, int "lines). The function takes the file name as the input parameter and puts the counts of characters and lines into the output parameters
