Demo Code

#include <iostream>
#include <locale>

int main()//  ww  w .  j a v a 2s  .c o  m
{
  const int maxlength {100};                // Array size
  char text[maxlength] {};                  // Array to hold input string

  std::cout << "Enter a line of text:" << std::endl;

  // Read a line of characters including spaces
  std::cin.getline(text, maxlength);
  std::cout << "You entered:\n" << text << std::endl;
  int vowels {};                         // Count of vowels
  int consonants {};                     // Count of consonants
  for(int i {} ; text[i] != '\0' ; i++)
  {
    if(isalpha(text[i]))                    // If it is a letter...
    {
      switch(tolower(text[i]))
      {                                     // ...check lowercase...
        case 'a': case 'e': case 'i': case 'o': case 'u':
          vowels++;                         // ...it is a vowel
          break;

        default:
          consonants++;                     // ...it is a consonant
      }
