int g;
cout<<"\t\t-----------------------------------"<<endl;
cout<<"\t\tMenentukan Nilai Ganjil dan Genap"<<endl;
cout<<"\t\t-----------------------------------\n\n"<<endl;
cout<<"Masukan nilai g : ";
cin>>g;
if (g % 2==0)
cout<<g<<" adalah bilangan Genap"<<endl;
else
cout<<g<<" adalah bilangan Ganjil"<<endl;
return 0;
}
