Lab 13

Vowel Program

CSCI 111 Programming and Algorithms I

NEW CONCEPTS: Successful completion of this lab incorporates the following new concepts.

switch statement

switch ( )

{

case 'x':

statement;

break; case 'y':

statement; break;

BLAH

default: statement;

}

tolower function

#include

locale loc;

tolower( , loc)

Task list:

1. Create a source code file named lab13.cpp.

2. Start by prompting the user for a sentence and saving it into a variable of type string.

3. Determine the frequency of each of the 5 vowels (i.e. a, e, i, o, u) plus other unknown characters.

4. The determination of vowels should be case-insensitive which means lower and upper-case letters are

treated the same. It is mandatory to use the tolower function. Using the or statement can produce the same result, but 0 credit will be earned.

locale loc;

tolower(sentence[c],loc))

{

5. The program should also use the switch statement. Again, 0 credit will be earned without the

implementation of the switch statement.

6. Refer to the expected output listing below.

SAMPLE OUTPUT

Please enter a sentence.

CSCI 111 is fun and ENJOYABLE!
