Program in c++ care transforma masura unui unghi introdus de la tastatura in radiani in grade,minute si secunde

Sa se introduca de la tastatura masura unui unghi in radiani.Programul trebuie sa calculeze masura acetuia in grade,minute si secunde.


#include<iostream.h>
 #include<conio.h>
#include<math.h>
void main()
{
clrscr();
int alfa;
cout<<"Introduceti masura unghiului alfa:";
cin>>alfa;
int grade,minute,secunde;
grade=(180*alfa)/M_PI;
minute=grade*60;
secunde=minute*60;
cout<<"transformare in grade"<<grade<<endl;
cout<<"transformare in minute"<<minute<<endl;
cout<<"tranformare in secunde"<<secunde<<endl;
getch();}
