Answer:

B. Methods and occasionally final attributes

Explanation:

In Computer programming, class members can be defined as the members of a class that typically represents or indicates the behavior and data contained in a class.

Basically, the members of a class are declared in a class, as well as all classes in its inheritance hierarchy except for destructors and constructors.

In a class, member variables are mainly known as its attributes while its member function are seldomly referred to as its methods or behaviors.

One of the main benefits and importance of using classes is that classes helps to protect and safely guard their member variables and methods by controlling access from other objects.

Therefore, the class members which should be declared as public are methods and occasionally final attributes because a public access modifier can be accessed from anywhere such as within the current or external assembly, as there are no restrictions on its access.

What is the missing line of code?

Ray Of Light [21]

Answer:

phrase[2:5]

Explanation:

Given:

The above code segment

Required

Which instruction returns 'u a'

First, we need to get the index of u in the phrase:

u is at the third position but in programming, index starts at 0.

So, u is at index 2

Next, we need to get the index of a in the phrase:

a is at index 4

One of the ways to return a sub string from a string in python is $string[start:stop+1]$

Where:

$start = 2$ ----- index of u

$stop = 4$ ----- index of a

phrase ---- The string variable

So, the instruction that returns 'u a' is: $phrase[2:5]$

Where 5 = 4 + 1

The scheme function (mult2-diff Ist) should take one argument, a list of numbers, and results in multiplying each number in the

JulijaS [17]

Answer:

The solution code is written in Python.

def mult2_diff(lst):
num_list = []
for x in lst:
num_list.append(x * 2)
diff = num_list[0]
for i in range(1, len(num_list)):
diff = diff - num_list[i]
print(diff)

Explanation:

Firstly, based on the requirement stated in the question, define a function mult2_diff() that takes one argument, lst, which is a list of numbers (Line 1).

This function is expected to multiply each number in the list by two and then followed with computing the difference. To do so, let's try to attempt the first function task, multiplying numbers. Create a new list, num_list, to hold the multiplied numbers (Line 2). Use a for loop to traverse through each number in the input list, lst, and multiply each of them by two and add it to the num_list (Line 4-5).

To attempt the second function task, create another variable, diff, to hold the value of calculated difference between the numbers in the num_list. Initialize diff with the first number in the num_list. Use a another for-loop to traverse through each number in the num_list starting with second index, 1, and calculate the difference between the diff and the current number extracted from the num_list through indexing.

At last print the output of diff (Line 11).
