ISC COMPUTER SCIENCE PRACTICAL 2016 QUESTION 3 : STRING


Write a program to accept a sentence which may be terminated by either '.', '?', or '!' only. The words may be separated by more than one blank space and are in UPPER CASE.
Perform the following tasks:
(a) Find the number of words beginning and ending with a vowel.
(b) Place the words which begin and end with a vowel at the beginning, following by the remaining words as they occur in the sentence.

Test your program with the sample data and some random data:

Example 1
Input : ANAMIKA AND SUSAN ARE NEVER GOING TO QUARREL ANYMORE.
Output : NUMBER OF WORDS BEGINNING AND ENDING WITH A VOWEL = 3
ANAMIKA ARE ANYMORE AND SUSAN NEVER GOING TO QUARREL
Example 2
Input : YOU MUST AIM TO BE A BETTER PERSON TOMORROW THAN YOU ARE TODAY
Output : NUMBER OF WORDS BEGINNING AND ENDING WITH A VOWEL = 2
A ARE YOU MUST AIM TO BE BETTER PERSON TOMORROW THAN YOU TODAY
