Question

我想生成代码；输入句子时，系统将仅显示这些句子的辅音字母。

我生成了代码，但该代码无法识别特殊的土耳其语元音字母就像İ，Ü，Ö作为常数字母一样。仅识别英语拉丁元音字母。

我该如何解决？

#include <stdio.h>
#include <string.h>
#include <time.h>
#include <wchar.h>

int vowel (char);

int main () 
{
    setlocale(LC_ALL, "Turkish");
    char s[100], t[100];
    int c, d = 0;
    printf ("Enter sentence vowels will ve removed:\n");
    gets (s);
    for (c = 0; s[c] != '\0'; c++)
    {
        if (vowel (s[c]) == 0)
        {           
            t[d] = s[c];
            d++;
        }
    }
    t[d] = '\0';
    strcpy (s, t);      
    printf ("Letters without vowels: %s\n", s);
    return 0;
}

int vowel (char ch) 
{
    if (ch == 'a' || ch == 'A'
     || ch == 'e' || ch == 'E'
     || ch == 'ı' || ch == 'I'
     || ch == 'i' || ch == 'İ'
     || ch == 'o' || ch == 'O'
     || ch == 'ö;' || ch == 'Ö'
     || ch == 'u' || ch == 'U'
     || ch == 'ü' || ch == 'Ü')
      return 1;
    else
      return 0;
}

我将其重写为使用wchar_t而不是char。

Ascii字符以单个字节（字符）表示。您可能需要将代码转换为使用wchar_t。

#include <locale.h>
#include <stdio.h>
#include <string.h>
#include <time.h>
#include <wchar.h>

int vowel (wchar_t); // <---- accepts wchar_t instead of char

int main ()
{
    setlocale(LC_ALL, "Turkish");
    /* To get it to work on https://www.onlinegdb.com/
     * use setlocale(LC_ALL,"en_US.UTF-8");
     * 
     */
    wchar_t s[100], t[100]; // <---- wchar_t instead of char
    int c, d = 0;
    printf ("Enter sentence vowels will ve removed:\n");

    // TODO : also check the return code. On error, it returns NULL.
    fgetws (s, 100, stdin); // <----- accepting wchar_t string

    for (c = 0; s[c] != '\0'; c++)
    {
        if (vowel (s[c]) == 0)
        {
            t[d] = s[c];
            d++;
        }
    }
    t[d] = '\0';
    // using memcpy instead of strcpy.
    // also see - http://www.cplusplus.com/reference/cwchar/wcscpy/
    memcpy (s, t, sizeof(t));
    printf ("Letters without vowels: ");
    for (c = 0; c < d; c++)
        putwchar(s[c]); // <---- print wchar_t character on terminal
    putwchar('\n');
    return 0;
}

int vowel (wchar_t ch)
{
    // I've prefixed an L - more than one byte.
    if (ch == L'a' || ch == L'A'
     || ch == L'e' || ch == L'E'
     || ch == L'ı' || ch == L'I'
     || ch == L'i' || ch == L'İ'
     || ch == L'o' || ch == L'O'
     || ch == L'ö' || ch == L'Ö'
     || ch == L'u' || ch == L'U'
     || ch == L'ü' || ch == L'Ü')
      return 1;
    else
      return 0;
}

样本输出

$ gcc test.c
$ ./a.out
Enter sentence vowels will ve removed:
abcdxyÖÜ
Letters without vowels: bcdxy

亲爱的@algrebe非常感谢您的快速回复。我在https://onlinegdb.com/BkxnoKZ2L上运行过代码，但是土耳其语元音在onlinegdb上显示为问号

Enter sentence vowels will ve removed:
