Answer:
a) range check
Explanation:
Validation can be defined as an automatic computer check that is designed to ensure any data entered is sensible, consistent, feasible and reasonable.
Basically, there are five (5) main validation methods and these includes;
I. Presence check: checks that the user enters (inputs) data into the field. It ensures a field isn't accidentally left blank.
II. Length check: checks that the data entered isn't too short or too long. It ensures that the data meets the minimum characters.
III. Type check: checks that the data entered is in the right format. For example, string, integer, float, etc.
IV. Check digit: checks that the digit entered is acceptable and consistent with the rest of the digits.
V. Range check: checks that the data entered is between the accepted lower (minimum) and upper (maximum) level.
Hence, range check is a validation type you would use to check that numbers fell within a certain range.
For example, 0 < x > 1000 is a range check.
Answer:
using System.IO;
using System;
class FineForOverdueBooks
{
static void Main()
{
Console.WriteLine("Enter the number of books user checked out: ");
int books = Convert. ToInt32(Console.ReadLine());
Console.WriteLine("Enter the number of overdue days: ");
int days = Convert. ToInt32(Console.ReadLine());
DisplayFine(books, days);
}
public static void DisplayFine(int books, int days) {
double amt = 0;
int d = days;
if(days>7) {
amt = (days-7) * .20 * books;
days = 7;
}
if(days > 0) {
amt = amt + days * .10 * books;
}
Console.WriteLine("The fine for {0} book(s) for {1} day(s) is {2}", books, d, amt);
}
}

Password is a very common approach to multisystem authorization. Passwords can be made up of a combination of letters, numbers, and special characters.
Anyone who has used a computer knows how to use a password, which is the most commonly used authentication method. Password-based authentication is the most simple for adversaries to exploit. Passwords are frequently reused, and guessable passwords are created using dictionary words and publicly available personal information. Two-factor authentication (2FA) is a security system that requires two distinct forms of identification to gain access to something. The first factor is usually a password, and the second is usually a text message with a code sent to our smartphone, or biometrics such as your fingerprint, face, or retina.
