Count the Vowels

[sevendash]

I need to create a program that has the user input a sequence of variables, and counts the variables. What I can't get is how to get each character from the string, and have it checked by my function that will tell if it's a variable or not.

Hi,

I think this program will satisfy your need.

#include <iostream.h>
#include <string.h>

#define VOWEL_CHARACTERS   "AEIOUaeiou"

int main(int argc, char* argv[])
{
   char
      szInput[100];  
      
   int
      nIndex = 0,
      nVowelsCount = 0,
      nStringLength = 0;

   cout << "****************** Count Vowels Characters ***********************\n";

   // Get the input.
   cout << "Enter the string : ";
   cin >> szInput;   

   // Get the length of the string.
   nStringLength = strlen(szInput);
   for(nIndex = 0; nIndex < nStringLength; nIndex++)
   {
      // Check whether it is a vowel character.
      if(strchr(VOWEL_CHARACTERS, szInput[nIndex]) != NULL)
      {
         // Increment the vowel characters count.
         nVowelsCount++;
      }      
   }
   // Print the result.
   cout << "The number of vowels characters present in the string " << szInput << " is " << nVowelsCount;

   return 0;
}
