Question

Data files will be provided fortesting, ranging from 3K to 260K. i.e. leaf.dat (leaf and stemdata file) Part 6 Write a program to find and output theindicated characters from your text file to the screen using asuitable format. Character types to count:    1. Upper-caseletters    2. Lower-caseletters    3. Digits    4. Punctuation usingispunct(char)    5. Other - not one of thetypes above Part 7 Modify your program from Part 6 to count theoccurrence of each type of character in your text file and outputthe character and its count. Part 8 Write a program to read each line of your textfile, count the number of "words" in each line, and at the end ofthe file, output the total number of words, the maximum number ofwords in one line, and the average number of words per line. Youwill define what a "word" is.
