Lab

Vowel Program (cont.)

CSCI 111 Programming and Algorithms I

0. Task list:

   1. Create a source code file named lab.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 the implementation of the switch statement.

1. 6. The goal of this program is to prompt the user for 3 sentences. For each sentence, calculate the frequency of each vowel

   7. After performing step 2 for all 3 sentences, determine which sentence has the most occurrences of a vowel and display the complete results as shown below.

   8. It is OK to assume that there is never a tie of the most popular letter for each sentence. This will save much time. Hint: So, ensure your test data follows this rule.

   9. Refer to the expected output listing below.

0. SAMPLE OUTPUT

   Enter sentence 0. I just wAnt to BANG on the drum all day LONG. Vowel statistics a: 4 e: 1 i: 1 o: 3 u: 2 unknown: 34 The most popular letter for sentence 0 is >a< having 4 occurrences. Enter sentence 1. The teacher told ME to stay after school. Vowel statistics a: 3 e: 5 i: 0 o: 4 u: 0 unknown: 29 The most popular letter for sentence 1 is >e< having 5 occurrences. Enter sentence 2. The BOSS is a jerk. Vowel statistics a: 1 e: 2 i: 1 o: 1 u: 0 unknown: 14 The most popular letter for sentence 2 is >e< having 2 occurrences.

The sentence with the most popular vowel is sentence 1 having 5 occurrences of letter >>e<<.
