Answer 1

供参考：

#include <stdio.h>

int main()
{
 FILE *fp;
 int  num=0,others=0,chars=0;
 char ch;
 fp=fopen("bookdata.txt","r");
 if(fp==NULL)
 {
    printf("Open file error!\n");
    exit (0);
 }
 while(1)
 {
    if(fscanf(fp,"%c",&ch) != 1) break;
    if(ch >= '0' && ch <= '9')
         num++;
    else if((ch >= 'A'&& ch <= 'Z')||(ch >= 'a'&& ch <= 'z'))
         chars++;
    else others++;
 }
 fclose(fp);
 printf("num:%d chars:%d others:%d\n",num,chars,others);
 
 return 0;
}
