C++ เครื่องคิดเลข ของผม ช่วยดูหน่อย...

คือผมไม่ใช่โปรแกรมเมอร์คับ (อยากเป็น 55+) ผมเรียนอยู่อเมริกาคับ ยุว grade11 (งงมั๊ย55)
แล้วผมเกิดสนใจ ภาษา C++ เลยลองเรียนเองตามเน็ต... เรียนได้ 3วันพอจะรู้แค่
1. cout/cin
2. loop
3. if
4. switch
ๆลๆ

แล้วพอรู้มาหน่อยนึงก้เกิดอยากลองทำโปรแกรม ดู... ลองผิดลองถูกพักนึงก้ได้โค๊ดตามนี้คับ...
