Bangun Prisma (Visual Studio 2008)

Praktikum kali ini di suruh membuat Prisma atau limas... berhubung nilai jika mngerjakan Prisma lebih besar, maka aku meillih prisma.

Prisma Segitiga

berikut source codenya.... INGAT!!!! ini menggunakan software "Visual Studio 2008" dengan beberapa library tambahan...
