(6 pts) Write a function called count_digits() that accepts an array of characters and the number of items in the array as parameters, and returns the number of digit characters in the array. For example, if the array contains [‘C’, ‘p’, ‘t’, ‘S’, ‘1’, ‘2’, ‘1’], then the function returns 3. Note: if the array does not contain any digit characters, then the function returns 0. You may use functions in <ctype.h>. Hint: isdigit (). 2. (9 pts) Write a function called remove_whitespace() that accepts an array of characters and the number of items in the array as parameters, removes all whitespace ( ' ' ) characters from the array, and returns the number of whitespace characters removed. For example, if the array contains [ 'C' , 'p' , 't' , 'S' , ' ' , '1' , '2' , '1' , ' ' , 'i' , 's' , ' ' , 'f' , 'u' , 'n' ] , then the function should remove the whitespace characters. The function must remove the whitespace characters by shifting all characters to the right of each whitespace character, left by one spot in the array. This will overwrite the whitespace characters, resulting in: [ 'C' , 'p' , 't' , 'S' , '1' , '2' , '1' , 'i' , 's' , 'f' , 'u' , 'n' ] . In this Instructor: Andrew S. O’Fallon
