Assigned: March 26, 2004

Due: April 2, 2004

1. Counting vowels (vowels.cpp)

Write a function countVowels that counts the number of vowels in a word (a string)

The function will accept one string parameter, and will return the number of vowels it finds

The function prototype (above main) should look like this:

int countVowels(string s);

Also write a suitable main program to demonstrate your function. Test it with the following strings:

String: Return value

College 3

Happy 1 (in this program, the letter y is not a vowel)

rhythm 0

2. Counting non-alphabetics (nonalpha.cpp)

Write a function countNonAlphas that counts the number of non-alphabetic characters in a word (a string). A non-alpha character is any character that is not a letter of the alphabet

The function will accept one string parameter, and will return the number of non-alphabetic characters it finds

The function prototype (above main) should look like this:

int countNonAlphas(string s);

Also write a suitable main program to demonstrate your function. Test it with the following strings:

String: Return value

3. Counting non-alphanumerics (nonalphanum.cpp)

Write a function countNonAlphanumerics that counts the number of non-alphanumeric characters in a word (a string). A non-alphanumeric character is any character that is not a letter of the alphabet or a number

The function will accept one string parameter, and will return the number of non-alphanumeric characters it finds

The function prototype (above main) should look like this:

int countNonAlphanumerics(string s);

Also write a suitable main program to demonstrate your function. Test it with the following strings:

String: Return value

R2D2 0
