C++关于文件的读写(续)

   上次,我们探讨了C++关于文件的读操作,这次继续写操作。写,顾名思义,就是把我们自己的东西放到文件中去。

我们举一个简单的例子,就不在乎它的排版问题了。

   #include<iostream>

   #include<fstream>

    using namespace std;

  int main()

  {

    char theme[50];

     int year;

    int month;

    int day;

    ofstream  outFile;

    outFile.open("1.txt");//新建文件

    cout<<"input:";

    cin.getline(theme,50);

    cout<<"year:";

    cin>>year;

    cout<<"month:";

    cin>>month;

    cout<<"day:"

    cin>>day;

    //控制台显示

    cout<<fixed;

    cout.precision(2);

    cout.setf(ios_base::showpoint);

    cout<<"date:"<<theme<<endl;

    cout<<"year:"<<year<<endl;

    cout<<"month:"<<month<<endl;

    cout<<"day:"<<day<<endl;

 

    //文件写入

    outFile<<fixed;//把上面所有的cout替换为outFile

    outFile.precision(2);

    outFile.setf(ios_base::showpoint);

    outFile<<"date:"<<theme<<endl;

    outFile<<"year:"<<year<<endl;

    outFile<<"month:"<<month<<endl;

    outFile<<"day:"<<day<<endl;

    return 0;  

  }

然后成功写入!
