Question

我无法在其他.cpp文件上进行声明，我尝试过，但找不到解决方案。我试图制作一个电影系统，并想在其他文件上声明内容。有可能吗？

这是我的代码：

  File "C:/Users/27357/Desktop/test.py", line 2, in <module>
    import pandas
  File "C:\python\lib\site-packages\pandas\__init__.py", line 55, in <module>
    from pandas.core.api import (
  File "C:\python\lib\site-packages\pandas\core\api.py", line 24, in <module>
    from pandas.core.groupby import Grouper, NamedAgg
  File "C:\python\lib\site-packages\pandas\core\groupby\__init__.py", line 1, in <module>
    from pandas.core.groupby.generic import (  # noqa: F401
  File "C:\python\lib\site-packages\pandas\core\groupby\generic.py", line 44, in <module>
    from pandas.core.frame import DataFrame
  File "C:\python\lib\site-packages\pandas\core\frame.py", line 88, in <module>
    from pandas.core.generic import NDFrame, _shared_docs
  File "C:\python\lib\site-packages\pandas\core\generic.py", line 70, in <module>
    from pandas.io.formats.format import DataFrameFormatter, format_percentiles
  File "C:\python\lib\site-packages\pandas\io\formats\format.py", line 48, in <module>
    from pandas.io.common import _expand_user, _stringify_path
  File "C:\python\lib\site-packages\pandas\io\common.py", line 512, in <module>
    def UnicodeReader(f, dialect=csv.excel, encoding="utf-8", **kwds):
AttributeError: module 'csv' has no attribute 'excel'

如果您是要在头文件中声明该结构而不是在main.cpp中声明，请制作一个头文件并说您将其命名为MovieItem.h

#ifndef Info_H
#define Info_H


struct Info{

string movie1,movie2,movie3,movie4; //MOVIE CHANGES
    movie1 = "Frozen II";
    movie2 = "Ip man 4";
    movie3 = "The Cave";
    movie4 = "Ejen Ali";

int Hall1,Hall2,Hall3,Hall4; //HALL NUM (???)
    Hall1 = 1;
    Hall2 = 2;
    Hall3 = 3; 
    Hall4 = 4;

string Time1,Time2,Time3,Time4; //TIME CHANGES
    Time1 = " 8.00AM";
    Time2 = "10.00AM";
    Time3 = " 2.00PM";
    Time4 = " 6.00PM";

double price1,price2,price3,price4 ; //PRICE CHANGES
    price1= 10; 
    price2 = 15;
    price3 = 8;
    price4 = 10;
};
#endif

使用

在您的main.cpp中包含此标头

#include "MovieItem.h"

然后，如@shubhgkr所述，在您的源代码中使用

struct Info Item1;

如何使对其他文件的声明成为可能？
