String program to count vowels

Implementation

Now, we shall see the actual implementation of the program −

#include <stdio.h>

int main() {
   char s[] = "TajMahal";     // String Given
   int i = 0;
   int vowels = 0;            // Vowels counter
   int consonants = 0;        // Consonants counter

   while(s[i++] != '\0') {
      if(s[i] == 'a' || s[i] == 'e' || s[i] == 'i' || s[i] == 'o' || s[i] == 'u' )
         vowels++;
      else
         consonants++;
   }

   printf("'%s' contains %d vowels and %d consonants.", s, vowels, consonants);

   return 0;
}

Output

Output of this program should be −

'TajMahal' contains 3 vowels and 5 consonants.
