Conversion from Basic to User-Defined variable

Consider the following example.

class Distance

                 {

                  public  : 

                                Distance(void)    // Constructor with no

                                 {                                               // argument

                                                   feet = 0;

                                                   inches = 0.0;

                                                 };

 

                                                Distance(float metres)

                                                 {

                                                   float f;                                     // Constructor with

                                                   f = 3.28 * metres;      // one argument

                                                   feet = int(f);         // also used for                          

                                                   inches = 12 * ( f - feet);// conversion                                             };

                                                                                void display(void)

                                                 {

                                                   cout << " Feet = " << feet <<",";

                                                   cout << " Inches = " << inches << endl;

                                                 };

  private :            

int feet;

float inches;

 };

void main (void)

                {

                   Distance d1 = 1.25;  // Uses 2nd constructor

                   Distance d2;                      // Uses 1st constructor 

                   float m;

        d2 = 2.0 ;             // Uses 2nd constructor

                   cout << " 1.25 metres is : " << d1.showdist() ;

                   cout << " 2.0  metres is :" << d2.showdist();

     }

Output :

                                1.25 metres is :FEET = 4 , INCHES = 1.199999        

                                2.0  metres is :FEET = 6 , INCHES = 6.719999         

The above program changes distance in metres ( basic data type) into feet and inches ( members of an object of class Distance ).

The declaration of first object d1 uses the second constructor and conversion takes place. Though, when the statement encountered is

d2 = 2.0;

The compiler first checks for an operator function for the assignment operator. If the assignment operator is not overloaded, then it uses the constructor to do the conversion.
