[問題] Xcode跑課程的範例一直Build Failed
開發平台(Platform): (Ex: VC++, GCC, Linux, ...)
Xcode Version 4.5
問題(Question)：
上禮拜週末去上台大資工開的C/C++基礎課程，上課是用VB教學，
課堂上的一個範例，回家用Xcode一直跑不出來？上課的時候老
師有提到conio.h如果到Mac的環境要改成curses.h，是改了以後
還是失敗，是哪裡有問題呢？
範例：輸入兩個數字, 再輸入+,-,*,/任一鍵, 根據輸入的
鍵內容顯示兩數計算結果
程式碼(Code)：(請善用置底文網頁, 記得排版)
#include <stdio.h>
#include <curses.h>
int main()
{
double a,b,ans;
char key;
printf("input two number:");
scanf("%lf %lf",&a,&b);
printf("press +,-,*,/:");
key=getch();
switch(key)
{
case '+':
ans=a+b;
break;
case '-':
ans=a-b;
break;
case '*':
ans=a*b;
break;
case '/':
ans=a/b;
break;
default:
printf("Undefined key\n");
return 0;
}
printf("%lf%c%lf=%lf\n",a,key,b,ans);
return 0;
}
