Kalkulator. Jak dzielić przez liczby całkowite?

0

Witam
Zrobiłem program kalkulator w Visual c++ 2010 i podczas dzielenia np. 13/2 wyświetla zamiast 6,5 to 6.

Proszę o pomoc.

  • Jak zrobić aby można było obsługiwać kalkulator z klawiatury? (Wpisywanie licz, * to mnożenie, = równa się itp).

Kod programu:
