重新定義struct tm errror。標題問題

錯誤：|| ===構建：Davis_project1中的調試（編譯器：GNU GCC編譯器）=== |重新定義struct tm errror。標題問題

c：\ mingw \ include \ time.h | 172 |錯誤：重新定義'struct tm'|

c：\ mingw \ include \ wchar.h | 87 |錯誤：'struct tm'的先前定義|建立失敗：2個錯誤，0個警告（0分鐘，0秒）=== |

我的程序運行得很好，直到我試圖爲srand函數添加ctime頭文件。從那以後，我重新獲得'struct tm'和'struct tm'錯誤的定義。互聯網告訴我它是一個標題問題。所以這裏是我的所有標題和cpp的下面。任何建議apprecciated。下面是我的主要cpp。我認爲這個問題是在這裏

#include <iostream> 
#include <string> 
#include "Club.h" 
#include <ctime>

int main(){ 

Club Club1; 
Club1.displayMenu();

Off topic：Usual nag。現在是2016年。時候把'srand'放在牀上。 [使用''代替。]（http://en.cppreference.com/w/cpp/numeric/random） – user4581301

值得再次編輯，以縮小cpp文件拒絕編譯太多的'struct tm'秒。 – user4581301

每當我谷歌隨機數字發生器，它的例子，我得到。我會看看。謝謝！ –

這是你的編譯器的問題，VC++沒有這個問題。

struct tm已經在wchar.h文件中定義（與cstring一起提供）。要解決這個錯誤，你可以使用getpid（）作爲種子。

// Both header-files are necessary for 'getpid()' 
#include <sys/types.h> 
#include <unistd.h> 

srand(getpid());

pid或progess-id在執行程序時不會改變，因此只設置一次種子。
