Answer:
Scanner can be used to read tokens from the console window (user input)
Explanation:
Scanner is a class used in some programming languages to obtain inputs from users.
It is mostly well developed in Java programming language and used exclusively for taking and obtaining inputs.
Scanner takes input in primitive types such as doubles, floats and integers. IT also takes string inputs.
Here is a code snippet where the class scanner is used:
Scanner input = new Scanner (System.in)
The code above creates an object of the scanner class
Answer:
The Anonymous Block will be:
1 DECLARE
2
3 lv_grade_row grade%rowtype;
4 lv_gr_avg grade.gr_t1%type;
5 lv_std_name varchar2(80);
6 cursor cursor_grade is select * from grade;
7
8 BEGIN
9
10 select avg(gr_t1) INTO lv_gr_avg from grade;
11 open cursor_grade;
12 fetch cursor_grade INTO lv_grade_row;
13
14 while cursor_grade%found loop
15
16 if
17 lv_grade_row.gr_t1>lv_gr_avg then lv_std_name :=
lv_grade_row.std_fname|| ' ' ||lv_grade_row.std_lname|| ' ' ||
lv_grade_row.gr_t1;
18 dbms_output.put_line(lv_std_name);
19
20 end if;
21 fetch cursor_grade into lv_grade_row;

Explanation:
An operating encrypts system a password for a given user, converting it into a representation that cannot be understood without the appropriate algorithm
3 encrypts
<u>Explanation:</u>
Normally end user login with user id account with password as login authorization or authentication to operate the system. There are some many technologies for login methods are used. Nowadays to login to operating system bio matric device is also been used.
In windows 10 pin also be used for login to operating systems. In Windows 10 operating system Hotmail accounts (clouds access also been used) so that related windows store or clipboard history are stores across the desktop and laptop.
Cracks: - some algorithm was used to crack password of login for operating system access.
Reverses- it a process or algorithm where reverse password or example: - 1234 where password in reverse process 4321.
Encrypts:- A password is encrypts with some calculation or string or some value. Cracking the password is used by using decrypts technology.
Decrypts is reverse logic applied based on encrypts technology.
