it depends
Explanation:
if you are hacking for a purpose that is benefiting the person being hacked, that is ethical hacking. ethical hacking is not illegal, as long as you get permission from the person being hacked.
if you hack someone without their knowledge, that is unethical hacking, and that is in many cases, a crime, and if it has enough of a detrimental effect on a companys process, it could land you into prison and earn you a hefty fine.
ethical hacking is good for testing a networks security, and if all is well, the ethical hacker shouldnt be able to get into a network if it is secured properly.

A
Explanation:
There's levels to it. As someone who use to play watchdogs anything is considered hacking.
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.
Answer: Following is a python code
def solveEquation(x,y,z):
res=z-y+(2*x) #stores expression's value
return res
solveEquation(2,1,4) #calls function
OUTPUT :
7
Explanation:
In the above code solveEquation is the function which takes three arguments x,y and z and their type is decided while calling the function and passing the values to these arguments. After the values are passed, an equation is written which is solved and the result is stored in variable res and then that variable's value is returned.
