   { cout << feet << "\'-" << inches << '\"'; }
   float square();             //member function
};
float Measure::square()          //return square of
{                              //this Measure
    float fltfeet = feet + inches/12;    //convert to float
    float feetsqrd = fltfeet * fltfeet;  //find the square
    return feetsqrd;               //return square feet
}
int main()

    Measure dist(3, 6.0);         //two-arg constructor (3'-6")
    float sqft;
    sqft = dist.square();          //return square of dist and square
    cout << "\nMeasure = "; dist.showdist();
    cout << "\nSquare = " << sqft << " square feet\n";
