Answer:
B) (x<=1)
Explanation:
Though this code given will run perfectly without any requirement of base case.But still we have to include a base case I will suggest (x<=1) because the value of x is decreased by one at each recursive call so it can handle it very well and it can handle negative values of x also if user enters it by mistake since factorial is for positive numbers only.
Answer:
False
Explanation:
This is not a good idea because the system is already compromise, you don't want auto blocking for retries, istead you could disconnect from the network while you fix the security problem.
Note: The remote access refers to the ability to access a computer or a network remotely, this allows you to access a system even if you are not physically there. Blocking for attempted login retries, mean that you block user access to the system if it tries to enter after been rejected the first time.
Answer:
grade = int(input("What grade are you in?")
if grade == 9:
print ("Freshman")
elif grade == 10:
print ("Sophomore")
elif grade == 11:
print ("Junior")
elif grade == 12:
print ("Senior")
else:
print ("Invalid")
Explanation:
You fail to provide the complete code. So, I will rewrite the code from scratch
The complete question requires that the level is printed based on the input grade.
The code has been added in the answer section.
The explanation is as follows:
[Thus gets input for grade]
grade = int(input("What grade are you in?")
[If grade is 9, this prints Freshman]
if grade == 9:
print ("Freshman")
[If grade is 10, then level is sophomore]
elif grade == 10:
print ("Sophomore")
[If grade is 11, then grade is Junior]
elif grade == 11:
print ("Junior")
[If grade is 12, then level is senior]
elif grade == 12:
print ("Senior")
[All other inputs are invalid]
else:
print ("Invalid")
Answer:
Inserting a tuple:
(10111, Ostrom, Economics, 110,000)
into the instructor table, where the department table does not have the
department Economics, would violate the foreign key constraint.
• Deleting the tuple:
(Biology, Watson, 90000)
from the department table, where at least one student or instructor
tuple has dept name as Biology, would violate the foreign key constraint.
employee (person name, street, city)
works (person name, company name, salary)
company (company name, city)
