國立暨南國際大學 103 學年度第一學期小考試卷

1. (10%) Determine whether the following code is correct or not.  If it is correct, predict its output.  If it is incorrect, point out the mistake(s).
   
   # Simple Decision
   a = 11
   b = 18
   n = 0
   if a > 11 :
       n = n + 1
   if b < 20 :
       n = n + 1
   print(n)
   
   
   
2. (10%) Consider the following decision strucutre:
   
   a, b, c, = eval(input('Enter three numbers: '))
   if a > b:
       if b > c:
           print("Spam Please!")
       else:
           print("It's a late parrot!")
   elif b > c:
       print("Cheese Shoppe")
       if a >= c:
           print("Cheddar")
       elif a < b:
           print("Gouda")
       elif c == b:
           print("Swiss")
   else:
       print("Trees")
       if a == b:
           print("Chestnut")
       else:
           print("Larch")
   print("Done")
   
   What will be the output that would result from each of the following possible inputs:
   
   (a) 3, 4, 5
   (b) 3, 3, 3
   
   
3. (10%) Determine whether the following code is correct or not.  If it is correct, predict its output.  If it is incorrect, point out the mistake(s).
   
   # Multi-Way Decision
   a = 11
   b = 18
   n = 0
   if a > 11 :
       n = n + 1
   elif b < 20 :
       n = n + 1
   else:
       n = n + 10
   print(n)
   
   
   
   
4. (10%) Determine whether the following code is correct or not.  If it is correct, predict its output.  If it is incorrect, point out the mistake(s).
   
   # Two-Way Decision
   a = 11
   b = 18
   n = 0
   if a > 11 :
       n = n + 1
   else
       n = n + 10
   if b < 20 :
       n = n + 1
   else:
       n = n + 10
   print(n)
