Jack,

You need to describe what you have accomplished so far and what problems you are having. In the C language you can compare characters as if they are numbers such as: char vowels[] = {'a', 'e', 'i', 'o', 'u'}; if('a' == vowels[0]) {/*...*/}

Considering this is homework I hate to just give you the code to do this but I will tell you it can be easily accomplished using a for loop, if statement, and a integer variable (to keep track of the number of vowels). Try on your own and then if you get stuck come back here and post your code and tell us what problems you are having then we can help you more.

Since this is homework you don't get code!

1) Define and clear a counter.
2) Start a loop through each character in the string
3) If the character is a vowel, increment the counter by one.
3a) This could be done with if...else if...else
3b) Or this could be done with a switch
4) After the loop completes the counter contains the vowel count.

Try this:

C#

char[] vowels = {'a','e','i','o','u'};
string input = txtInput.Text.ToLower();
char[] splittedResult = input.Split('');
int ctr = 0;

foreach(char result in splittedResult)
{
   switch(result)
   case vowels[0]:
   case vowels[1]:
   case vowels[2]:
   case vowels[3]:
   case vowels[4]: ctr++;
                   break;
   default: break;
}

The result of ctr will be the count of vowels.

Please mark as answer and vote 5 if this solved your problem
