counting vowels in string (c language)

[ashpats]

Hey everyone,

I am supposed to write a program that counts the number of vowels in string of characters.
It must include "Struct counter_t (it must be declared as in the code i've written)" and function "int CountVowels (IN text[], OUT Count)". the OUT parameter must be of type counter_t. I've written the code but it doesn't seem to work. Can someone help me please???

-------------------------------------------------------------------------------------------------------------
#include <stdio.h>

typedef struct {
int a;
int e;
int i;
int o;
int u;
}counter_t;

int CountVowels (char text[], counter_t Count);

int main ()
{
char text[100];
counter_t Count;
Count.a = 0;
Count.e = 0;
Count.i = 0;
Count.o = 0;
Count.u = 0;
printf ("Text\n");
gets(text);
CountVowels(tex t, Count);
printf("a = %d\n", Count.a);
printf("e = %d\n", Count.e);
printf("i = %d\n", Count.i);
printf("o = %d\n", Count.o);
printf("u = %d\n", Count.u);
fflush (stdin);
getchar ();
return 0;
}

int CountVowels (char text[], counter_t Count)
{
int i;
for (i = 0; text[i] != '\0', i++)
{
switch(text[i])
{
case 'a': Count.a++; break;
case 'e': Count.e++; break;
case 'i': Count.i++; break;
case 'o': Count.o++; break;
case 'u': Count.u++; break;
}
}
return (Count);
}

I see that you were right that the function was supposed to return an int. Sorry about that. I think the Count parameter is supposed to be passed by reference so you can modify it in the function but not return it, and the int the function returns is the total number of vowels; the sum of all the variables in the struct. So the prototype would be:

int CountVowels (char text[], counter_t* Count);

And at the end of the function, you add up all the individual vowel counts and return that.

Here's a link to a reference for the tolower function.

[curiously enough]

You don't need to get rid of return, just write return (*Count); instead of return(Count); so not to return an adress.

thanx guys. i finally finished it.
the line
Count = CountVowels(tex t, Count);
was the problem. i simply changed it to
CountVowels(tex t, &Count);
and it appears to be workin'
