Counting vowels

**rmrjr22** · 11-13-2012

Thats the body of the while loop, no?
Ah, nvr mind. Moved ++i; to end of loop.
reads vowels now...
but i still am unsure on how to input more than once sentence

This is what you wanted.

Code:

    while((sentence[i] = getchar()) != '\n')
    {
        if(sentence[i] == 'a' || sentence[i] == 'e' || sentence[i] == 'i' || sentence[i] == 'o' ||sentence[i] == 'u')
        {
            ++keystrokes;
            ++letters;
            ++vowels;
        }
        else
        {
            if (isalpha(sentence[i]) == 1)
            {
                ++keystrokes;
                ++letters;
            }
            else
            {
                ++keystrokes;
            }
        }


        i++;
    }

I addressed that in post #7. Apparently we've gotten nowhere with that.

Or better yet...

Code:

    for(i=0; ((sentence[i] = getchar()) != '\n'); i++)
    {
        if(sentence[i] == 'a' || sentence[i] == 'e' || sentence[i] == 'i' || sentence[i] == 'o' ||sentence[i] == 'u')
        {
            ++keystrokes;
            ++letters;
            ++vowels;
        }
        else
        {
            if (isalpha(sentence[i]) == 1)
            {
                ++keystrokes;
                ++letters;
            }
            else
            {
                ++keystrokes;
            }
        }
    }

Or even better :P

Code:

    for(i=0; ((sentence[i] = getchar()) != '\n'); i++)
    {
        ++keystrokes;
        
        if (isalpha(sentence[i]) == 1)
        {
            ++letters;
            
            if(sentence[i] == 'a' || sentence[i] == 'e' || sentence[i] == 'i' || sentence[i] == 'o' ||sentence[i] == 'u')
            {   
                ++vowels;
            }
        }
    }

So far this works great... minus being unable to input more than one sentence when the program runs

Code:

#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>


int main(int argc, char *argv[])
{
  int keystrokes = 0;			//Number of keystrokes.
  int letters = 0;					//Number of total letters.
  int vowels = 0;				//Number of vowels.
  int i = 0;
  char sentence[9999];					//Chararacter array specified to users input.


 while((sentence[i] = getchar()) != '\n')
	     
  {
	  if(sentence[i] == 'a' || sentence[i] == 'e' || sentence[i] == 'i' || sentence[i] == 'o' ||sentence[i] == 'u') //stating vowels
	  {
		  ++keystrokes;
		  ++letters;
		  ++vowels;
	  }
	  else
	  {
		  if (isalpha(sentence[i]) == 1) // if character is true
		  {
			  ++keystrokes;
			  ++letters;
		  }
		  else
		  {
			  ++keystrokes;
			  i++;
		  }
	  }
  }


  
                                                                  
  printf("SAMPLE OUTPUT, for EACH sentence above:\n");
  printf(" Program#5 CS110.\n");
  printf("Keystrokes %d \n", keystrokes); 
  printf("Alpha Characters %d \n", letters); 
  printf("Vowels %d \n", vowels);


   
  
  return 0;
}

Code:

Hello friend

SAMPLE OUTPUT, for EACH sentence above:
 Program#5 CS110.

Keystrokes 12
Alpha Characters 5
Vowels 4

Works great, eh?

@Click_Here: Be careful of the return value of "isalpha()" - it might be better to just make sure it's true (or not zero), instead of equal to one.

Return value: A value different from zero (i.e., true) if indeed c is an alphabetic letter. Zero (i.e., false) otherwise.

I did rush it :P

Yes, that would be much better.

Looking at my sketch file where I copy/paste and run code for here, I seem to have done it before closing the file (?!) - I didn't repost the code though -> I remember now: I didn't think that it was worth reposting.

Your code is not working, because you are incrementing 'i' only if it's not a vowel and is not alpha. What is more annoying is that in a rare laps of judgement, I showed you where to do it in post 17
