Trolls are attacking your comment section!
A common way to deal with this situation is to remove all of the vowels from the trolls' comments, neutralizing the threat.
Your task is to write a function that takes a string and return a new string with all vowels removed.
For example, the string "This website is for losers LOL!" would become "Ths wbst s fr lsrs LL!".
Note: for this kata y isn't considered a vowel.
#include <string.h>
#include <stdlib.h>
int is_vowel(char c) {
if (c == 'a' || c == 'A'
|| c == 'e' || c == 'E'
|| c == 'i' || c == 'I'
|| c == 'o' || c == 'O'
|| c == 'u' || c == 'U')
return 1;
else
return 0;
}
char *disemvowel(const char *str) {
int num = 0;
for (int i = 0; str[i]; i++) {
if (is_vowel(str[i]))
num++;
}
char *ret = malloc(strlen(str) - num + 1);
int i = 0;
int j = 0;
while (str[i]) {
if (is_vowel(str[i])) {
i++;
continue;
}
ret[j++] = str[i++];
}
ret[j] = 0;
return ret;
}
나보다 길게 푼 사람 못 봤다 ...^^ 진짜 문제 오천개는 풀어야겠다
