    FILE *fp=fopen("F:\\微云同步盘\\c\\series.txt","r");
   
      char ch;
      while((ch=getc (fp)) != EOF)        //逐行读取fp所指向文件中的内容
        {
        
        fscanf(fp,"%s,%d\n",a,b);        //格式化输入           
          printf("%s,%d\n",a,b);

}


int main(int argc, char *argv[])
{

    screentofile();
   
    fieltoscreen();
   
    getch();
    return 0;
}

输入是：外框，68
输出就变乱码？
为什么呀？有没有大神帮看看？

      char ch;
      while((ch=getc (fp)) != EOF)        //逐行读取fp所指向文件中的内容
        {
        
        fscanf(fp,"%s,%d\n",a,b);        //格式化输入           
          printf("%s,%d\n",a,b);   
          }

改为：

//char ch;
//while((ch=getc (fp)) != EOF)
{
    fscanf(fp,"%[^,],%d",a,&b);
    printf("%s,%d\n",a,b);   
}
