错误：|| === Build：在Davis_project1中调试（编译器：GNU GCC编译器）=== |

c：\ mingw \ include \ time.h | 172 |错误：重新定义＆＃39; struct tm＆＃39; |

c：\ mingw \ include \ wchar.h | 87 |错误：以前定义＆＃39; struct tm＆＃39; |

|| ===构建失败：2个错误，0个警告（0分钟，0秒（秒））=== |

我的程序运行完全正常，直到我尝试为srand函数添加ctime标头。从那以后，我得到了结构的重新定义。以前的定义＆＃39; struct tm＆＃39;错误。互联网告诉我它的标题问题。所以这里是我的所有标题和下面的cpp。任何建议都是适用的。下面是我的主要cpp。我认为这个问题在这里

#include <iostream>
#include <string>
#include "Club.h"
#include <ctime>
using namespace std;

int main(){

Club Club1;
Club1.displayMenu();
Club1.processInput();

Answer 1

这是编译器的问题，VC ++没有这个问题。

struct tm已在wchar.h文件中定义（随cstring一起提供）。要解决此错误，您可以使用getpid（）作为种子。

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

srand(getpid());

pid或progess-id在程序执行期间不会改变，因此只设置种子一次。

重新定义struct tm errror。标题问题
