Switch Case, Menu, Parallelogram, Artan ve Azalan Yıldız Piramitleri

[mustaphos]

Merhaba.
Bu C programı öncelikle bir değer ister. Değer 1 ile 3 arasında oluncaya kadar da değer sormaya devam eder.
1 ise parallelogram üretir. (Sonra bir değer daha istiyor.)
2 ise artan yıldız piramidi
3 ise azalan yıldız piramidi
İyi çalışmalar.
