ISC 2016 QUESTION

Write a program to accept a sentence which may be terminated by either ‘.’, ‘?’ or ‘!’ only. The words are separated with a blank space, and are in uppercase.

Perform the following:

Find the number of words beginning and ending with a vowel.
Place the words which begin and end with a vowel at the beginning, followed 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.

Example 3:
INPUT: LOOK BEFORE YOU LEAP.
OUTPUT: NUMBER OF WORDS BEGINNING AND ENDING WITH A VOWEL: 0
LOOK BEFORE YOU LEAP.

Example 4:
INPUT: HOW ARE YOU@
OUTPUT: Sentence must begin with ‘.’, ‘!’ or ‘?’.
