Mình thích hiển thị như thế này.
//----------------------HIEN THI-----------------------
void PhanSo :: Inps(PhanSo ps)
{
//ps=Lamgonps(ps);
if (ps.tu==ps.mau) cout<<"1";
else if (ps.tu==0) cout<<"0";
else if (ps.mau==1) cout<<ps.tu;
else cout<<ps.tu<<"/"<<ps.mau;
};

ở phép Trừ hai phân số: nếu trừ 2 phân số bằng nhau là treo máy luôn! hok bie't hay la' tai ma'y mi'nh nu^a ??? thanks
