Lab

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! Vowel statistics a: 2 e: 2 i: 2 o: 1 u: 1 unknown: 22
