Consider the C library function

char * strtok ( char * str, const char * delimiters ); 

This function stores the starting address of the next token to parse in a static local variable. The objective of this assignment is to appreciate the issues associated with using static local variables.

Write a C program to determine the average number of words per line by using strtok. You will write a function that does the following:

1. tokenizes a string containing multiple sentences into individual sentences (using strtok);

2. calls another function that returns the number of words in a sentence by tokenizing the string containing a sentence into individual words; and

3. calculates the average number of words per sentence.
