Chinese Zodiac (shio / Shēngxiào) C++ code

The Shēngxiào, literally "birth likeness", is also known in English as the 
Chinese zodiac. Zodiac derives from the similar concept in western astrology 
and means "circle of animals". The Chinese zodiac is a scheme 
and systematic plan of future action that relates each 
year to an animal and its reputed attributes according to a 
12-year cycle, and it remains popular in several East Asian countries including China, Vietnam, Korea and Japan.

here is the code:

#include <iostream>

#include <conio.h>

using namespace std;

main()

{

      int a,b,c,d;

      cout<<"Enter Your Birthday Date  = ";cin>>a;

      cout<<"Enter Your Birthday Month = ";cin>>b;

      cout<<"Enter Your Birthday Year  = ";cin>>c;

      d=((c-4)%12);

      cout<<endl;
