Computers and Technology
1 answer:

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.

When do you use a for loop instead of a while loop? (There may be more than one answer.)
statuscvo [17]

Answer:

- You know how many times you want the loop to run.

- When there is a defined start and end.

Explanation:

Required:

When to use for instead of while loop?

First, it should be noted that both for loop and while loop are used for iteration. However, depending on the scenario; there is preference on one to the other.

The basic syntax of for loop is:

for(start;end;condition)\{\}

<em>The condition could either be increment or decrement</em>

The basic syntax of while loop is:

while(condition)\{\}

<em>The condition could be any condition whatsoever</em>

Analyzing the options one after the other.

1. How many times the loop to run.

The for loop is preferred here because of the simplicity of the for loop.

2. & 3. Both the for and while loops are used for code repetition and to perform number calculations

4. Defined start and end.

From the syntax of the for loop

for(start;end;condition)\{\}

<em />

A for loop has a definite start and end in its basic syntax and is more preferable to use instead of a while loop.

<em />

<em />

Hence, 1 & 4 answer the question

Write a program with class name Digits that prompts the user to input a positive integer and then outputs the number reversed an
mr Goodwill [35]

Answer:

Written in Python:

inputnum = int(input("User Input: "))

outputnum = 0

total = 0

while(inputnum>0):

     remainder = inputnum % 10

     outputnum = (outputnum * 10) + remainder

     inputnum = inputnum//10

     total = total + remainder

print("Reverse: "+str(outputnum))

print("Total: "+str(total))

Explanation:

This prompts user for input

inputnum = int(input("User Input: "))

This initializes the reverse number to 0

outputnum = 0

This initializes total to 0; i.e. sum of each digit

total = 0

The following iteration gets the reverse of user input

<em>while(inputnum>0): </em>

<em>      remainder = inputnum % 10 </em>

<em>      outputnum = (outputnum * 10) + remainder </em>

<em>      inputnum = inputnum//10 </em>

<em>      This adds each digit of user input</em>

<em>      total = total + remainder </em>

This prints the reversed number

print("Reverse: "+str(outputnum))

This prints the sum of each digit

print("Total: "+str(total))
