    int n = 12;
    int is_vowel;
    int i;
    char* p = s;
    char* q = p;

    while (*p != '\0') {
        is_vowel = 0;
        for (i=0; i<n; i++) {
            if (*p == vowels[i]) {
                is_vowel = 1;
                break;

        }
        if (!is_vowel) {
            *q = *p;
