Answer: All of the answers are correct EXCEPT "An instance of a class cannot be changed after it is created.

Explanation: I've done the problem. Also, if you have an instance of a class, you can no longer change it. It is frozen in time as that one instance. If had a class defining pets and you made an instance dogA where the pet was a brown medium sized dog, dogA would always be a brown medium sized dog. I think, at least.

Assume the existence of a Window class with a function getWidth that returns the width of the window. Define a derived class Win

Pepsi [2]

Answer:

Following are the code in the C++ Programming Language.

//define class and inherited the parent class

class WindowWithBorder : public Window

{

//access modifier

private:

//set integer variable

int borderWidth;

//set integer variable

int windowWidth;

//access modifier

public:

//definition of the constructor that accept an integer type argument

WindowWithBorder(int);

//definition of the function

int getUseableWidth();

};

//set constructor outside the class

WindowWithBorder::WindowWithBorder(int y)

{

//initialization in integer variable from function

windowWidth = getWidth();

//initialization in integer variable from the argument list

borderWidth = y;

}

//set function from outside the class

int WindowWithBorder::getUseableWidth()

{

//return output

return windowWidth - borderWidth;

}

Explanation:

Here we define a class "WindowWithBorder" which inherit their parent class "Window", inside the class.

Set two integer data type private variables "borderWidth" and "windowWidth".
Write the definition of the "windowWidth" class constructor that accept the integer type argument list.
Write the definition of the function "getUseableWidth()" which is integer type.

Then, we define constructor outside the class which accept the integer type argument list "y" inside it.

we initialize in the variable "windowWidth" from the function "getWidth()".
Initialize in the variable "borderWidth" from the argument of the constructor.

Finally, we define function in which we perform the subtraction of the variable "windowWidth" from the variable "borderWidth" and return it.

Which of the following tools and techniques shows theimpacts of one decision over another as well as the probability andcost of

Nezavi [6.7K]

Answer: Probability/impact risk matrix

Explanation: Probability/impact risk matrix is type of matrix that defines the probability as well as impact that depicts whether the risk is low ,high or moderate.

Impact matrix is sort of tool which helps in conversion of any plan into a action. Probability matrix help in defining the chances in defining the risk.The positioning of the impact value of risk is plotted on the vertical axis and performance value on the horizontal axis.

Thus probability/impact matrix is the correct tool for the problem mentioned in the question.

See explaination

Explanation:
