Data Type Conversion || C++

Data Conversion

1.  Conversion between Basic to User Defined Data Types

/* conversion from basic data type to user defined data type */

/* to convert NPR to Dollar */

#include<iostream>

#include<conio.h>

using namespace std;

class conv{

     double dol,cent;

     public:

               conv()

               {

                         

               }

               conv(float fnpr)

               {

                          dol=fnpr/103.7;

                          cent=int((fnpr/103.7-int(fnpr/130.7))*100);

                          dol=int(fnpr/103.7);

                         

               }

               void show()

               {

                          cout<<dol<<"$ "<<cent<<" Cent";

               }

};

int main()

{

     conv dollar;

     float npr;

     cout<<"NPR:"<<endl;

     cin>>npr;

     dollar=npr;

     dollar.show();

     getch();

}

2.  Conversion from User Defined to Basic Data Types

/* conversion from user defined data type to basic data type */

#include<iostream>

#include<conio.h>

using namespace std;

class dollar{

     float dol, cent;

     public:

               dollar(int d=0, int c=0)

               {

                          dol=d;

                          cent=c;

               }

               operator float()

               {

              

                          return((dol+cent/100)*103.7);

              

               }

};

int main()

{

     dollar d1(3,40);

     float np;

     np=d1;

     cout<<"Money in NPR::"<<np;

}
