Sort Program Help

• Re-implement the readLine() function so that it no longer makes use of fgets(). Instead, process the input on a given line character-by-character. • Provide code which will create a data structure similar to argv to hold all of the words to be sorted. Use malloc() to ensure that each entry has just the required number of bytes needed to store the words. The final entry in your array should be the NULL pointer. • Implement a sort() function which will rearrange the words in sorted order. To swap two words in your array, note that only a pair of pointers need to move. The strings themselves, once established, will never move.
