JUMLAH, KURANG, KALI, BAGI

Algoritma Jumlah, Kurang, Kali, Bagi {menampilkan hasil jumlah, kurang, klai, bagi }

Deklarasi : p : integer x  : integer y : integer hasil : double

Deskripsi : ostr<<"TOTAL JUMLAH : "<<p.x+p.y<<endl; ostr<<"TOTAL KURANG : "<<p.x-p.y<<endl; ostr<<"TOTAL KALI : "<<p.x*p.y<<endl; ostr<<"TOTAL BAGI : "<<p.x/p.y<<endl;
