/* C++ Program to execute basic operations on Fractions, using Template Metaprogramming Created by - Kinshuk Vasisht - 27/09/2017 Classes - : 1) Fraction - Define Fractions 2) Multiply - Multiply Numerator of 'Frac' with 'Vl' 3) Mult - Multiply Num and Den of 'F' with 'C' 4) HCF - Get the HCF of X and Y 5) LCM - Convert F1 and F2 to a same base 6) Simplify - Simplify Fraction, Divide N&D by HCF. 7) Add - Add F1 and F2 8) Sub - Subtract F1 and F2 9) Mul - Multiply F1 and F2 10) Div - Divide F1 and F2 */ #include using namespace std; #define cast(D) static_cast(D) template struct Fraction { static const long N = a; static const long D = b; static void Print() {cout< struct Multiply { typedef Fraction result; }; template struct Mult { typedef Fraction result; }; template struct HCF { static const long result = \ HCF::result; }; template struct HCF { static const long result = X; }; template struct LCM { typedef typename Mult::result Xres; typedef typename Mult::result Yres; }; template struct Simplify { static const long hcf = \ HCF::result; typedef Fraction<(F::N/hcf),\ (F::D/hcf)> result; }; template struct Add { typedef LCM M; static const long N = \ M::Xres::N + M::Yres::N; static const long D = M::Yres::D; typedef typename Simplify>\ ::result result; }; template struct Sub { typedef LCM M; static const long N = \ M::Xres::N - M::Yres::N; static const long D = M::Yres::D; typedef typename Simplify>\ ::result result; }; template struct Mul { static const long N = X::N * Y::N; static const long D = X::D * Y::D; typedef typename Simplify>\ ::result result; }; template struct Div { static const long N = X::N * Y::D; static const long D = X::D * Y::N; typedef typename Simplify>\ ::result result; }; int main() { cout<<"Calculation - Series 1 : "< Half; Half::Print(); cout<<"\nCalculating Fraction's Value\n"; cout<<"Fraction's Value - "; Half::Value(); cout<<"\nMultiplying Fraction by 3\n"; cout<<"New Fraction - "; typedef Multiply<3,Half>::result NewFrac; NewFrac::Print(); cout<<"\nCalculating Fraction's Value\n"; cout<<"Fraction's Value - "; NewFrac::Value(); cout< One6; One6::Print(); cout<<"\nCalculating Fraction's Value\n"; cout<<"Fraction's Value - "; One6::Value(); cout<<"\nMultiplying Fraction by 4\n"; cout<<"New Fraction - "; typedef Multiply<4,One6>::result NewF2; NewF2::Print(); cout<<"\nSimplifying the Fraction\n"; cout<<"New Fraction - "; typedef Simplify::result NewFracS; NewFracS::Print(); cout<<"\nCalculating Fraction's Value\n"; cout<<"Fraction's Value - "; NewFracS::Value(); cout< Ten6; Ten6::Print(); cout<<"Fraction's Value - "; Ten6::Value(); cout<<"\nOriginal Fraction B - "; typedef Fraction<3,19> Three19; Three19::Print(); cout<<"Fraction's Value - "; Three19::Value(); cout<<"\n\nCalculating Sum : \n"; typedef typename Add\ ::result Sum; cout<<"Sum (A+B) - "; Sum::Print(); cout<<"Sum (Value) - "; Sum::Value(); cout<<"\nCalculating Difference : \n"; typedef typename Sub\ ::result Dif; cout<<"Difference (A-B) - "; Dif::Print(); cout<<"Difference (Value) - "; Dif::Value(); cout<<"\nCalculating the Product : \n"; typedef typename Mul\ ::result Pro; cout<<"Product (A*B) - "; Pro::Print(); cout<<"Product (Value) - "; Pro::Value(); cout<<"\nCalculating the Quotient : \n"; typedef typename Div\ ::result Quo; cout<<"Quotient (A/B) - "; Quo::Print(); cout<<"Quotient (Value) - "; Quo::Value(); cout<
