Overloading the >> Operator for Your Own Classes


For the latest documentation on Visual Studio 2017 RC, see Visual Studio 2017 RC Documentation.

Input streams use the extraction (>>) operator for the standard types. You can write similar extraction operators for your own types; your success depends on using white space precisely.

Here is an example of an extraction operator for the Date class presented earlier:

istream& operator>> (istream& is, Date& dt)  
    is>> dt.mo>> dt.da>> dt.yr;  
    return is;
