call by value should be used whenever the called function does not need to modify the value of the caller’s original value.
Answers
The given statement "Call by value should be used whenever the called function does not need to modify the value of the caller's original value" is TRUE because his method passes a copy of the original value to the function, ensuring that the original value remains unchanged.
Call by value is a method of passing arguments to a function where a copy of the original value is sent, ensuring that the called function does not modify the caller's original value.
This technique is beneficial when the function only requires data for computation without altering the actual value. By using call by value, the original data remains intact, providing a safer programming approach and preventing unintentional side effects
. In summary, call by value should be used when the function does not need to modify the caller's original value, allowing for efficient and secure operations in your program.

write a recursive function that takes as a parameter a nonnegative integer and generates the following pattern of stars. if the nonnegative integer is 4, then the pattern generated is: javascript
Answers
Write a recursive function that takes as a parameter a nonnegative integer and generates the following pattern of stars. If the nonnegative integer is 4, then the pattern generated is. We can use the below code to generate the pattern of stars.
Here, we have a recursive function named starPattern() that takes a non-negative integer as a parameter. Inside the function, we are using two variables, one to represent the number of stars and the other for the count of the total number of stars that are printed.We have checked if the input integer is greater than 0 or not, if it is not then the function will terminate. And, if it is greater than 0, then the function calls itself again and again. This is known as a recursive call.
Now, we are multiplying the number of stars (n) by 2 to get the total number of stars to be printed in each row. Then we are adding the count with the number of stars and printing them.In recursion, a function calls itself again and again to perform a task. A recursive function has two cases: Base case and Recursive case. The base case is used to terminate the recursion. It is the simplest possible case, where the function stops calling itself. The recursive case is the condition that calls the function again. It makes the function calls itself again and again, until the base case is met.

What is the difference between HDMI 1 and HDMI 2
Answers
Explanation:
the main differences between HDMI 1 and HDMI 2 are the maximum resolution, color depth, audio channels, and bandwidth they support. HDMI 2 provides significantly higher resolution, color depth, and audio capabilities than HDMI 1, making it ideal for use with newer, higher-end devices and content. However, it is important to note that not all devices support HDMI 2, so compatibility should be checked before connecting devices together.
MORE DETAILED INFORMATION
HDMI 1 and HDMI 2 are different versions of the HDMI (High Definition Multimedia Interface) standard that are used to connect audiovisual devices, such as TVs, monitors, and gaming consoles, to each other.
HDMI 1 was first introduced in 2002 and supports a maximum resolution of 1080p (1920 x 1080 pixels) at 60 Hz with up to 8-bit color depth. It also supports up to 8 channels of digital audio, such as Dolby Digital and DTS. HDMI 1.4, which was released in 2009, added support for 3D content and an Ethernet channel for internet connectivity.
HDMI 2, on the other hand, was introduced in 2013 and provides significant improvements over HDMI 1. It supports a maximum resolution of 4K (3840 x 2160 pixels) at 60 Hz with up to 12-bit color depth, which provides a wider range of colors and greater detail in images. It also supports high dynamic range (HDR) content, which enhances the contrast and brightness of images. In addition, HDMI 2.0 supports up to 32 channels of digital audio, including advanced formats like Dolby Atmos and DTS:X, and can carry up to 18 Gbps of bandwidth, which allows for smoother playback of high-resolution content.

Coding Problem please review my work!
Part 1: Design a Class
You’ll design a class named Car that has the following fields:
yearModel—An Integer that holds the car’s year model
make—A String that holds the make of the car
speed—An Integer that holds the car’s current speed
The class should have the following constructor and other methods:
The constructor should accept the car’s year model and make as arguments. These values should be assigned to the object’s yearModel and make fields. The constructor should also assign 0 to the speed field.
Design appropriate accessor methods to get the values stored in an object’s yearModel, make, and speed fields.
The accelerate method should add 5 to the speed field each time it’s called.
The brake method should subtract 5 from the speed field each time it’s called.
My coding ( it's in pseudocode!)
Class Car
Private Interger yearModel
Private String Make
Private Interger Speed
//Constructor
Public Module Car (Interger y, String m, Interger s)
Set yearModel = y
Set Make = m
Set Speed = s
End Module
//Mutators
Public module setYearModel (Interger y)
Set yearModel = y
End Module
Public module setMake (String m)
Set Make = m
End Module
Public module setSpeed (Interger s)
Set Speed = s
End Module
//Accesors
Public Function Interger getYearModel()
Return yearModel
End Function
Public Function String getMake()
Return make
End Function
Public Function Interger getSpeed()
Return speed
End Function
//Accelerate
Public Module accelerate()
set speed = speed + 5
End Module
//Brakes
Public Module brake()
set speed = speed - 5
End Module
End Class
Part 2: Design a Program
You’ll create both pseudocode and a flowchart to design a program that creates a Car object and then calls the accelerate method five times.
After each call to the accelerate method, get the current speed of the car and display it.
Then, call the brake method five times. After each call to the brake method, get the current speed of the car and display it. Take a screenshot of the results after your fifth time calling the method.
My coding ( it's in Pseudocode!)
Module Main()
Call accelerate(5)
End Module
Module accelerate(Interger times)
If times > 0 Then
Display " The car has increased its speed by 5"
Display "The cars current speed is, 'speed'.
Call accelerate (times - 1)End if
End Module
Module Main()
Call brake(5)
End Module
Module brake (Interger times)
If times > 0 Then
Display " The cars brake has been Increased by 5"
Display " The cars current brake is, 'brake'.
Call brake(times - 1)
End If
End Module

Assume that x and y are boolean variables and have been properly initialized. The result of evaluating the expression above is best described as (B) always false.
What is the Boolean variables about?The logical AND operator && returns true only when both operands are true. For example, true && true is true, true && false is false, and false && false is false.
The expression (x && y) is true only when both x and y are true, and the expression ! (x & & y) is the negation of this, which is true only when x and y are not both true.
Therefore, the overall expression is only true when x and y are both true and also not both true at the same time, which is not possible. As a result, the expression is always not true.
