        ch = (char) getchar();
        if ((ch >= 'a' && ch <= 'z') || (ch >= 'A' && ch <= 'Z')) {
            if (ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u' ||
                ch == 'A' || ch == 'E' || ch == 'I' || ch == 'O' || ch == 'U') {
                ++vowels;
            } else {
                ++consonants;
            }
        }

    printf("Number of consonants = %d\n", consonants);
