我正在制作一个类似于口袋妖怪的游戏类型的程序.我们有一个锦标赛课程,跟踪几个团队(它自己的类),其中包括宠物(它自己的类),不同种类的宠物是CPet的子类.
我们正在尝试将文件名传递给main,从主传递该文件名到Tournament类.在Tournament类中,我们打开文件：
14 //Construct a tournament
15 CTournament::CTournament(const char *Filename){
16 //opening file
17 ifstream inFile(Filename,ios::in);
18 if(inFile.bad()){
19 cout << "File error" << endl;
20 return ;
21 }
22 //get Teamlist for tournament
23 while(!(inFile.eof())){
24 CTeam* temp = new CTeam;
25 temp->ParseTeam(inFile);
26
27 TeamList.push_back(temp);
28 }
29 }
在这里,我们将文件传递给CTeam.ParseTeam,它看起来像：
30 void CTeam::ParseTeam(std::istream in){
31 string readline;
32 getline(in,readline);
33 this->TeamName = readline;
34 while(!(in.eof())&&(readline != " " || readline != "/n"))
35 {
36 getline(in,readline);
37 this->Parse(readline);
38 }
39 }
我们收到错误：
In file included from /usr/include/c++/4.4/ios:39,from /usr/include/c++/4.4/ostream:40,from /usr/include/c++/4.4/iostream:40,from CTournament.h:11,from CTournament.cpp:8: /usr/include/c++/4.4/bits/ios_base.h: In copy constructor 'std::basic_ios<char,std::char_traits<char> >::basic_ios(const std::basic_ios<char,std::char_traits<char> >&)': /usr/include/c++/4.4/bits/ios_base.h:790: error: 'std::ios_base::ios_base(const std::ios_base&)' is private /usr/include/c++/4.4/iosfwd:47: error: within this context /usr/include/c++/4.4/iosfwd: In copy constructor 'std::basic_istream<char,std::char_traits<char> >::basic_istream(const std::basic_istream<char,std::char_traits<char> >&)': /usr/include/c++/4.4/iosfwd:53: note: synthesized method 'std::basic_ios<char,std::char_traits<char> >&)' first required here CTournament.cpp: In constructor 'CTournament::CTournament(const char*)': CTournament.cpp:25: note: synthesized method 'std::basic_istream<char,std::char_traits<char> >&)' first required here CTournament.cpp:25: error: initializing argument 1 of 'void CTeam::ParseTeam(std::istream)'
我知道有一个类似的问题,他没有包括fstream.我们已将它包含在两个头文件中.
我想也许这是一个没有将正确的类型传递给PraseTeam的问题,但我找不到任何非常具体的关于如何将文件传递给ParseTeam以验证我是否正确执行的问题.
提前致谢.
解决方法
您需要通过引用传递流,因为流通常不是可复制的：
void CTeam::ParseTeam(std::istream &in)
