ISC COMPUTER SCIENCE PRACTICALS 2008 ~ Vowels & Words Count

ISC COMPUTER SCIENCE PRACTICALS 2008 ~ Vowels & Words Count in Strings
A sentence is terminated by either “ . ” , “ ! ” or “ ? ” followed by a space.
Input a piece of text consisting of sentences. Assume that there will be a
maximum of 10 sentences in a block.
Write a program to:
(i)  Obtain the length of the sentence (measured in words) and the frequency
     of vowels in each sentence.
(ii) Generate the output as shown below using the given data

Sample data:

INPUT
HELLO! HOW ARE YOU? HOPE EVERYTHING IS FINE. BEST OF LUCK.
OUTPUT

Sentence    No. of Vowels    No. of words
----------------------------------------------------------

2        5        3 
3        8        4
