[閒聊] 讓我賺點錢吧@@"

[air7925 (雅力克修)]

嗯...有鑒於最近手頭有點緊...

就讓我PO點豪洨文賺點P幣吧"o(￣▽￣)o"

不想看者請自離，傷到眼睛不要怪我~(￣▽￣)~(＿△＿)~(￣▽￣)~(＿△＿)~






















Enum方法 讀檔+計算複數 (我知道大家都會了...就說讓我賺點p幣咩ε(┬┬＿┬┬)3)

{

 float temp;

 fp1 = fopen("file.txt","r");
 fp2 = fopen("out.txt","w");

 if (fp1 == NULL)
     exit (1);

 printf ("Loading.........\n");

 while ((fscanf(fp1,"%f",&temp))!=EOF)    /* 讀取檔案裡的資料 */
 {
  arr[i]=temp;
  i=i+1;
 }
 printf("\nLoad End......\n");

 fclose (fp1);
}

   scanf ("%c",&c);
   fflush (stdin);

 switch (e)
 {
  case 43:
    complex_Add (x,y);  break;
  case 45:
    complex_Sub (x,y);  break;
  case 42:
    complex_Mul (x,y);  break;
  case 47:
    complex_Div (x,y);  break;
 }

 system ("pause");

 return 0;

}




















YA~終於打完了.....雖然很亂 不過那不是我的目的v(￣︶￣)y
不曉得這樣打可以賺多少???( ￣ c￣)y▂ξ

順帶一題，在設定ASCII碼那邊，如果設定值和輸入字串的碼不同，
則在switch那邊將不會動作，這點要注意，編碼請自行參照課本附錄F
