<em>Form validation</em> is adopted to prevent the abuse of web form by malicious users, data that are not properly validated causes or leads to security vulnerabilities, thereby making a website to be at a risk of being attacked by malicious users.
<em>Validation rules</em> checks that the data a user enters in a record meets the specify standards before the user is allowed to save the record, a validation rule evaluates the data in one or more fields and return it as true or false.
<em>JavaScript form validation can be used to check all required fields, the steps are adopted are:</em>
<em>i) Basic validation − The form is first checked to make sure that all the mandatory fields are filled.</em>
<em>ii) Data format validation −The data that is entered is then checked for correct form and value before allowing to proceed, submit or save the record.</em>
The elements in a string type array will be initialized to "Null".
The answer is Salted Password Hashing. The process is similar to hashing., but with a twist. A random value is introduced for each user. This salt value<span> is included with the password when the hash value is calculated and is stored with the user record. Including the salt value means that two users with the same password will have different password hashes.</span>
Answer:
Here is the Python program which has a function sum_scores:
def sum_scores(score1, score2, score3, score4):
sum = score1 + score2 + score3 + score4
print(sum)
sum_scores(14,7,3,0)
Explanation:
- Method sum_scores takes four arguments, score1, score2, score3, score4.
- The sum variable adds these four scores and stores the value of their addition.
- Lastly print statement is used to print the value stored in sum variable which is the value obtained by adding the four scores.
- Last statement calls the sum_scores method and passes four values to it which are 14,7,3,0
- The output of the above program is:
- 24
- If you want to use return statement instead of print statement you can replace print(sum) with return sum. But in order to display the sum of the scores you can replace sum_scores(14,7,3,0) with print(sum_scores(14,7,3,0))
- The program along with the output is attached as a screenshot.
