コードの最後の部分でofstream変数に問題があります。オフストリームから情報が失われるのを防ぐにはどうすればよいですか?この問題は、プログラムの最後の部分で発生します。
これが私が得ているものです:

これが私の印刷機能です:エラーはここにある必要がありますが、それを修正する方法がわかりません
void movieType::printMovieInfo(char* outFileName)
{
std::ofstream outFile;
if(!outFile.is_open())
outFile.open(outFileName, std::ios::app);
outFile<<name<<" "<<year<<" "<<genre<<" "<<length<<" "<<rank;
outFile<<" "<<weight<<" "<<year<<" "<<votes<<std::endl;
}
編集者:
void movieType::printMovieInfo(std::ofstream& outFile)
{
outFile<<name<<" "<<year<<" "<<genre<<" "<<length<<" "<<rank;
outFile<<" "<<weight<<" "<<year<<" "<<votes<<std::endl;
}
そしてメインの最後の部分で:
ij.printMovieInfo("printList.txt");
に変更されました
ij.printMovieInfo(outFile);
これが私の主な機能です:問題はプログラムの最後に生成されます
