哪位大侠帮偶编一段译码程序   用c++builder语言  有重谢  要求对一个文件进行打开然后读取

Memo->lines->LoadFile("ddd.txt");

什么意思  我看不懂呀

void __fastcall TForm1::N14Click(TObject *Sender)
{
FILE *f;
int a=0,b;
int c[8];
char h;
if ((f = fopen("C:\\Program Files\\Borland\\CBuilder6\\Bin\\FILENAME.C_Str", "rt"))
       == NULL)
   {
      fprintf(stderr, "Cannot open input file.\n");
   }

h = fgetc( f );
while(!feof(f))
 { while(h!=' ')
   {
     b=h;
     a=a+b;
   }
   c[8]=h;
   while(h== '\n')
   {
     switch(a)
     {
      case 195: C_S=c[8]; break;
      case 67:  C=c[8];   break;
      case 70:  F=c[8];   break;
      case 150:  SC=c[8];  break;
      case 204:  CALL=c[8];  break;
      case 208:  Q_R=c[8]; break;
     }
     printf("\n");
   }
   if ((f = fopen("FILENAME.C_Str", "rt"))
       == NULL)
     break;
 }
int  fclose(FILE *f);

}




这是那段程序  不知道哪个循环出错了  运行起来老是未响应
