Need help with counting " Y" as a vowel

Expand Post »

I am trying to get this code working for extra credit, but I unfortunately only have 40 minutes until it is due:rolleyes:. I would like to know how to do this program, whether I turn it in or not. The letter "Y" can be considered a vowel if there is not a vowel immediately before or immediately after the "y", otherwise it should be considered a consonant. I have everything working except for the Y being counted as a vowel when it is next to consonants.

C++ Syntax (Toggle Plain Text)
#include <iostream>
#include <cctype>
using namespace std;
 
int Y(char string[], int ctr, int vowel);
int length = 0;
int vowel = 0;
 
int main()
{
    char string[50] = "";
    cout << "Please enter a string of 50 characters or less: ";
    cin.getline(string, 50);
    length = strlen(string);
 
    for(int ctr = 0; ctr < length; ctr++)
    {
        string[ctr] = tolower(string[ctr]);
 
 
        if(string[ctr] == 'a' || string[ctr] == 'e' || string[ctr] == 'i' || string[ctr] == 'o' || string[ctr] == 'u')
        {    
            vowel++;
 
            if(string[ctr] == 'y')
            {    
                vowel = Y(string, ctr, vowel);
            }
        }
 
        if(string[ctr] == ' ')
        {
            vowel++;
        }
 
    }
    cout << "\nThe string you entered was: "<< string << endl;
    cout << "You entered " << (length - vowel) << " consonants in that string." << endl;
}

    bool flag1 = false;
    bool flag2 = false;

unfortunately for you the time expired 6 hours ago. Lesson learned: don't wait until the last minute to get help.

Re: Need help with counting " Y" as a vowel

Well, I had a major project that was due as well as finals all this week, so I did not do the extra credit until everything else was finished. Anyway, I would still like to know how to do it.

Re: Need help with counting " Y" as a vowel

here is something just off the top of my head -- untested and uncompiled.

C++ Syntax (Toggle Plain Text)
 
int isvowel(char c)
{
   if(c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u')
          return TRUE;
   return FALSE;
}
 
...
...
if( string[ctr] == 'y' )
{
   if( !isvowel(strin[ctr-1]) && !isvowel(strin[ctr+1]) 
   {
          // y is a vowel
   }
}
int isvowel(char c)
{
   if(c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u')
          return TRUE;
   return FALSE;
}

...
...
if( string[ctr] == 'y' )
{
   if( !isvowel(strin[ctr-1]) && !isvowel(strin[ctr+1]) 
   {
          // y is a vowel
   }
}

your program also needs to verify that (ctr-1) >= 0 && (ctr+1) <= length of the string.
