[問題] 書上範例編譯失敗(數值分析 使用C語言)
範例來自數值分析 使用C語言 程曉旭 耿魯靜 張海 王勇
http://www.wunanbooks.com.tw/product/9789865836108
第二章 複數的四則運算
開發平台(Platform):ubuntu 13.04 ,gcc 4.7.3
main function: http://ideone.com/YUs2Os
other functions: http://ideone.com/m2LeIL
http://ideone.com/hJrvlR
我將main function 和 other functions 放在同一資料夾
然後 gcc 編譯 main function，出現以下錯誤訊息：
c_comp_examplel.c:1:20: fatal error: c_comp.h: No such file or directory
compilation terminated.
如果我將main function的 #include "c_comp.h" 去掉也無法編譯
會產生以下的錯誤訊息：
In file included from c_comp_divide.c:12:0,
from c_comp_examplel.c:6:
c_comp_product.c:12:8: error: redefinition of ‘struct c_comp’

我想請問的是～
是我的編譯方式有問題嗎?
或者是書上有範例有錯?
謝謝大家耐心看完

範例光碟 還有書本裡並沒有附此檔案
我google "c_comp.h"之後 也是一頭霧水

十分感謝大家的建議
(尤其是S大熱心修改code,我會仔細比較您和書中範例的差異)
原本範例中printf(" ")裡的雙引號還是全形的 printf(” ”），
我後來修改過才PO上來給大家看 囧rz

我剛才隨手從後面翻了兩個範例，其中一個還是compile不過，
另外一個作者忘記附在電子檔裡了。
(書中有寫電子檔的名稱，可是我從光碟找不到該檔案 囧rz)

感謝推薦,我借到了 Numerical Recipes in C; Algorithms_3rd; Algorithms.in.c;
以上三本書,
不過都沒有含範例程式 不知道哪本比較詳盡好讀
另外d大提到碁峰的書 請問有特別推哪一本嗎?
