Answer: site consistency
Answer:
B) Site Consistency
Explanation:
Write some code that assigns True to the variable is_a_member if the value assigned to member_id can be found in the current_members list. Otherwise, assign False to is_a_member. In your code, use only the variables current_members, member_id, and is_a_member.
Answers
Answer:
current_members = [28, 0, 7, 100]
member_id = 7
if member_id in current_members:
is_a_member = True
else:
is_a_member = False
print(is_a_member)
Explanation:
Although it is not required I initialized the current_members list and member_id so that you may check your code.
After initializing those, check if member_id is in the current_members or not using "if else" structure and "in" ("in" allows us to check if a variable is in a list or not). If member_id is in current_members, set the is_a_member as True. Otherwise, set the is_a_member as False.
Print the is_a_member to see the result
In the example above, since 7 is in the list, the is_a_member will be True

Implement a class Balloon that models a spherical balloon that is being filled with air. The constructor constructs an empty balloon. Supply these methods:
void addAir(double amount) adds the given amount of air.
double getVolume() gets the current volume.
double getSurfaceArea() gets the current surface area.
double getRadius() gets the current radius.
Supply a BalloonTester class that constructs a balloon, adds 100cm^3 of air, tests the three accessor methods, adds another 100cm3 of air, and tests the accessor methods again.
Answers
Answer:
Here is the Balloon class:
public class Balloon { //class name
private double volume; //private member variable of type double of class Balloon to store the volume
public Balloon() { //constructor of Balloon
volume = 0; } //constructs an empty balloon by setting value of volume to 0 initially
void addAir(double amount) { //method addAir that takes double type variable amount as parameter and adds given amount of air
volume = volume + amount; } //adds amount to volume
double getVolume() { //accessor method to get volume
return volume; } //returns the current volume
double getSurfaceArea() { //accessor method to get current surface area
return volume * 3 / this.getRadius(); } //computes and returns the surface area
double getRadius() { //accessor method to get the current radius
return Math.pow(volume / ((4 * Math.PI) / 3), 1.0/3); } } //formula to compute the radius
Explanation:
Here is the BalloonTester class
public class BalloonTester { //class name
public static void main(String[] args) { //start of main method
Balloon balloon = new Balloon(); //creates an object of Balloon class
balloon.addAir(100); //calls addAir method using object balloon and passes value of 100 to it
System.out.println("Volume "+balloon.getVolume()); //displays the value of volume by getting value of volume by calling getVolume method using the balloon object
System.out.println("Surface area "+balloon.getSurfaceArea()); //displays the surface area by calling getSurfaceArea method using the balloon object
System.out.println("Radius "+balloon.getRadius()); //displays the value of radius by calling getRadius method using the balloon object
balloon.addAir(100); //adds another 100 cm3 of air using addAir method
System.out.println("Volume "+balloon.getVolume()); //displays the value of volume by getting value of volume by calling getVolume method using the balloon object
System.out.println("Surface area "+balloon.getSurfaceArea()); //displays the surface area by calling getSurfaceArea method using the balloon object
System.out.println("Radius "+balloon.getRadius()); } } //displays the value of radius by calling getRadius method using the balloon object

Which of the following is NOT a reason to include comments in programs?

c. Comments help document how code was written for other programmers to use
d. Comments enable programmers to track their work throughout the development

Explanation:
The reason for this is because in a code when you use the comment out the compiler will skip over it and will not do anything and will skip it. So the comment can help the computer do anything!
HOPE THIS HELPED MAKE ME THE BRAINLIST!
Using programming concepts, the option that is NOT a reason to include comments in a code is:
a. Comments help the computer decide whether certain components of a program are important.
-------------------------
Usually, codes are very long, and each person is responsible for a part of the problem. The parts have to be intervened with each other, and thus, sometimes a programmer will have to look at another part of the code, not coded by him. Thus, for the programmer and other people working in the project to understand, comments are important.Additionally, the comments are used to help the programmers debug their own code, as they can go part by part and see what is done in each part, also helping them work throughout the development process.In a program, there may be some components that end up not being necessary, but this is not decided by comments, and thus, option A is not a reason to include comments in programs.A similar problem is given at https://brainly.com/question/13527834

Explanation:
In the above given C++ language modified code, four-string variable " name, address, MSG_YES, and MSG_NO", four integer variable "item, quantity, size, and i", and "integer and double" array is defined, that holds values.
In the string and integer variable "name, address, and item, quantity", we input value from the user-end and use the while loop, which uses the if block to check the "item and quantity" value from the user end and print its respective value.

Write a program named palindromefinder.py which takes two files as arguments. The first file is the input file which contains one word per line and the second file is the output file. The output file is created by finding and outputting all the palindromes in the input file. A palindrome is a sequence of characters which reads the same backwards and forwards. For example, the word 'racecar' is a palindrome because if you read it from left to right or right to left the word is the same. Let us further limit our definition of a palindrome to a sequence of characters greater than length 1. A sample input file is provided named words_shuffled. The file contains 235,885 words. You may want to create smaller sample input files before attempting to tackle the 235,885 word sample file. Your program should not take longer than 5 seconds to calculate the output
In Python 3,
MY CODE: palindromefinder.py
import sys
def is_Palindrome(s):
if len(s) > 1 and s == s[::-1]:
return true
else:
return false
def main():
if len(sys.argv) < 2:
print('Not enough arguments. Please provide a file')
exit(1)
file_name = sys.argv[1]
list_of_palindrome = []
with open(file_name, 'r') as file_handle:
for line in file_handle:
lowercase_string = string.lower()
if is_Palindrome(lowercase_string):
list_of_palindrome.append(string)
else:
print(list_of_palindrome)
If you can adjust my code to get program running that would be ideal, but if you need to start from scratch that is fine.
