Answer 4

KrOW my code is not well organized, I'm sorry for that.

My code works fine when the while condition is (respond=='N' && respond =='n')

But when the condition becomes (respond=='N' || respond =='n')
The code loops infinitely

Why is that happening?

Isn't or (||)more logical than and(&&)?
