Please help. The code must be in C programming language (not C ++ or java etc)

8.20 (Counting the Number of Words in a String ) Write a program that inputs several lines of text and uses strtok to count the total number of words. Assume that the words are separated by either spaces or newline characters and that there are at most 10 lines with each line being no longer than 80 characters . Stop taking more input lines if the user enters 10 lines or an empty line. Remember to include the C string header to use strtok and other string -related functions.
