kalkulator sederhana c++

kalkulator ini dibuat dengan algoritma yang sederhana, meskipun belum sempurna seperti kalkulator biasanya yang kita gunakan, tapi ya lumayan lah untuk menghitung, dan juga buat menyelesaikan tugas kuliah..
ini tampilan screen shoot programnya :

nah seperti itu lah kalkulator sederhana dengan c++

dan disini anda bisa download programnya :
DISINI
