c - C-如何从不带数字，特殊字符(，。？＆)的文件中提取单词？

我想从文件中提取单词，然后发送到数组。我是用fscanf完成的。但是，它需要数字，字符（，。％＆＃！？）和其他东西。如何控制此语句？

int main(void)
{
  char path[100];
  printf("Please, enter path of file: "); scanf("%s",&path);
  FILE *dosya;
  char kelime[1000][50];
  int i=0;

  if((dosya = fopen(path,"r")) != NULL)
  {
    while(!feof (dosya))
    {
        fscanf(dosya,"%s",&kelime[i]);
        i++;
    }
  }
  else{printf("Not Found File !");}
  fclose(dosya);
}

最佳答案

使用"%[]"区分字母和非字母。

#define NWORDS (1000)
char kelime[NWORDS][50];

size_t i;
for (i=0; i<NWORDS; i++) {
  // Toss ("*" indicates do not save) characters that are not ("^" indicates `not`) letters.
  // Ignore return value
  fscanf(dosya, "%*[^A-Za-z]");

  // Read letters
  // Expect only a return value of 1:Success or EOF:no more file to read
  // Be sure to limit number of characters read: 49
  if (fscanf(dosya, "%49[A-Za-z]", kelime[i]) != 1) break;
}

// do something with the `i` words
