Using radio waves, Radio Frequency Identification (RFID) technology can identify individuals or things.

<h3>What is Radio Frequency Identification?</h3>

Using radio waves, Radio Frequency Identification (RFID) technology can identify individuals or things. It is possible to read data from a wireless device or "tag" from a distance without making physical contact or needing a clear line of sight using certain devices.
Since the 1970s, various forms of RFID technology have been made commercially available. Car keys, employee identification, medical billing and history, toll road tags, and security access cards all contain it today and are now a common part of our daily lives.
The proximity and vicinity types of RFID technology are both used by the US government for border management:

Documents with proximity RFID capability can be securely and precisely read by authorized readers up to 20 to 30 feet away.
Documents with proximity RFID capability can only be read from a few inches away and must be scanned close to an authorized reader.

Only a number pointing to the data kept in secure databases is stored on the RFID card instead of any personal information.

erastova [34]

Answer:

The function definition to this question can be given as:

Function definition:

void printAttitude(int x1) //define function printAttitude.

{

//nested else-if statements

if(x1==1)

//if block

cout<<"disagree"<<endl;

//message

else if(x1==2)

//else if block

cout<<"no opinion"<<endl;

//message

else if(x1==3)

//else if block

cout<<"agree"<<endl;

//message

else

cout<<" ";

}

Explanation:

In the above method definition firstly, we define a method that is "printAttitude". In this method, we pass an integer variable that is "x1". This function does not return any value because its return type is void. In this method, we use nested else-if statements. The description of these conditions can be given as:

In the if block we check the variable x1 value is equal to 1 If this condition is true. It will print "disagree" otherwise it will go to else-if block.
In the else-if block, we check the variable x1 value is equal to 2 if the condition is true. It will print "no opinion". otherwise, we will go to another else-if block.
In this block, we check the variable x1 value is equal to 3 if this condition is true. It will print "agree".otherwise it will go to else block.
In the else block it will print nothing.

<h3>What is operating system?</h3>

An operating system (OS) exists as the program that, after being initially loaded into the computer by a boot program, contains all of the other application programs on a computer. The application programs create use of the operating system by completing requests for services through a specified application program interface (API).

A GUI utilizes windows, icons, and menus to carry out commands, such as opening, deleting, and moving files. Although a GUI operating system is especially navigated using a mouse, a keyboard can also be utilized via keyboard shortcuts or arrow keys.

The GUI, a graphical user interface, exists as a form of user interface that permits users to interact with electronic devices via graphical icons and audio indicators such as primary notation, instead of text-based UIs, typed command labels, or text navigation.

Hence, Compared to using a command line, an benefit to using an operating system that employs a GUI exists you do not have to memorize complicated commands.
