Answer:
current_price = int(input("Enter the current price: "))
last_months_price = int(input("Enter the last month's price: "))
print("Current price is: " + str(current_price) + ", Last month's price was: " + str(last_months_price))
print("The change since last month is: " + str(current_price - last_months_price))
print("The estimated monthly mortgage is: " + str(current_price * 0.051))
Explanation:
Get the inputs for the current price and last month's price
Print the prices
Calculate and print the change, current_price - last_months_price, since last month
Calculate, using given formula, and print the estimated monthly mortgage
Answer:
The answer to the given question is the option "b".
Explanation:
In the question option b is correct. It is given that class bClass is a derived class that inherits the base class that is aClass. In the c++ programming language we use the (:) for the perform in inheritance. "Driving a new class from an old class is called inheritance". and other options are not correct that can be described as follows:
- In option (a) and option(c) the scope resolution operator is used, The scope resolution operator does not use for the single level inheritance it is used for declaring the outline function as well as it is also used for initialized the static variable.That.s why the option(a) and option(c) is incorrect.
- In the option(d) the base class i.e "aClass" inherit the derived class i.e "bClass " this is wrong so this option is incorrect
That's why the option "b" is correct.
Answer: Explanation:
Salting alters the hash of a password so that it does not physically match the hash of another password. A salt and password are concatenated and processed with a cryptographic hash function. Salt prevents use of rainbow and hash tables to attacking and cracking passwords.
For example, a user has the password, "password000" and is put through a SHA1 hash. In the password database, all of the users with the password "password000" will have the exact same hash, because of the nature of hashing functions. So, if an attacker breaches the database and brute force the password of the user mentioned above, he could look for all the hashes that match the original user's and would know their passwords are also "password000".
By applying a salt, the password hashes would no longer be identical to one another, even though the actual password is still the same. This requires the attacker to go in and attempt to brute force the second password (which has a different salt), even though it may be the same as the first.
In conclusion, it prevents an attacker from uncovering one password and subsequently uncovering multiple others.
