Conversion from a basic type to a class type may be
achieved using SUITABLE CONSTRUCTORS IN CLASS.


EX:
class distance
{
int feet;
float inch;


public:

distance(float p) //costructor to concert basic type to
class type
{

feet= (int) p;
inch=(p-feet)*12;
}


void show()
{
cout<<"feet="<<feet;
cout<<"inch="<<inch;
}
};

void main()
{
distance d1=1.75;

d1.show();
}

out put

feet=1;
inch=9;
