Assuming you are working in a team for a company, do you think there are any ethical issue if you know that one of the team members is actually interviewing with other company. The team member does not want to inform the team of his or her intention to leave until he or she gets an offer. Do you think it is ethical that you also decide to act ignorant about it and not telling your team lead or manager of this fact ? Let's assume your team also have a deadline coming up, it will more than likely be too late for the team manager to find a replacement for the team member that wanting to get away.

PYTHON Program
Problem Statement: Write a Python program that processes information related to a rectangle and prints/displays the computed values.
The program will behave as in the following example. Note that in the two lines, Enter length and Enter width, the program does not display 10.0 or 8.0. They are values typed in by the user and read in by the program. The first two lines are text displayed by the program informing the user what the program does.
This program reads in the length and width of a rectangle. It then prints the area and perimeter of the rectangle.
Enter length: 10.0
Enter width: 8.0
Length 10.0 width 8.0 area 80.0 perimeter 36.0
Create two pieces of data (other than what we have above) that would serve as input to the program; then write down what the output would be. We show a sample first. (We are ignoring here the first two lines of text that would always be displayed.)
Sample Input 0: Length 20 width 5
Expected Output for the above data
Length 20.0 width 5.0 area 100.0 perimeter 50.0
Create your own data now.
Input 1: length width Expected Output for the above data
Input 2: length width Expected Output for the above data
Before proceeding, get OK from your instructor or the tutor.
Using the Input-Processing-Output approach, write down the pseudo code for the program.
Before proceeding, get OK from your instructor or the tutor.
Convert the pseudo code to Python code. Use ideas from below.
Pseudo code
Input an integer into x
Input a number with a decimal point into x Set x to a + b
Set x to a * b
Print a, b, c
Print weight and mass annotated
Print a message
Python code
x = int(input(‘Enter a number: ‘))
x = float(input(‘Enter a number: ‘))
x = a + b
x = a * b
print(a, b, c)
print(‘weight is’, weight, ‘mass is’, mass) print(‘whatever message
you want’)
Test and debug the program. For testing, use the data you created in Step 1.
Show your source program and demonstrate it to your instructor. Get his/her signature below.

Write this program in a C++ language Calculate the ideal age of a spouse. Enter either m or f from the keyboard in lower case. You may use string data for the gender. Convert the gender to upper case
Enter an age from the keyboard, probably an integer
You will need prompts telling the user what to enter.
Use an IF statement to determine if the person is a male or female. You do one calculation if the person is a male else you do another calculation if the person is a female.
Use a loop where you enter this data (loop for 1 to 6 ) so you will only have to run the program 1 time instead of 6 times.
m 28
m 70
m 18
f 32
f 60
f 13
For each set of data, print out the Gender, age, and Ideal Spouse's age, along with the following messages when they apply (the messages will be in the last column):
If a male over 60, print “robbing the cradle.”
If a male under 25, print “too young to be married”
if a female over 60, print “a gold digger”
if a female < 19 print “jail bait”
Plato's formula. A little bit out of date. You will be a gold digger or robbing the cradle if your age is over 40 because back then people only lived to be about 35 or so on the average.
For a male, his ideal spouse’s age is his age/2+7
For a female, her age*2-14
So, inside the loop
1. Input from the keyboard either m or f and an age
2. convert the m or f to upper or upper case
3. enter age from keyboard
4. Use an if to determine if user is a male or female. Use the appropriate syntax for your language. Calculate Ideal age.
5. Print the Gender as “Male” or as “Female”, and the age, and the ideal age you calculated.
6. Then print any matching messages on the same line
7. Accumulate the total idea age of a male spouse and of a female spouse and the count of males and females.
8. When you exit the loop the print the average idea age of a spouse for a male and the average ideal age of a spouse for a female.
if gender=="M"
do male calculation
else
do female calculation
remember two = signs for comparison
You will need braces for code blocks

Cpp challenge
Description
The purpose of this challenge is to use various flow control structures. This challenge uses techniques for displaying formatted output, simulating a payment structure for paying off outstanding debt such as a credit card or any kind of interest-bearing loan.
Requirements
cout << setw(5) << months << setw(10) << start_bal ... (of course, you can't actually use ellipses in the code. That's just an indicator that you can continue with whatever data and formatting you need)
Do Not Use
You may not use the break statement to terminate any loops
Sample Interaction / Output
What is the outstanding balance? 2000
What is the APR? 24
How much do you pay every month? 125

Modularity
Note: The documentation you’ll be looking at for this part of the lab was written for
professional programmers, not programming novices, so it may include a number of
references to complex technical topics or details. Don’t be surprised, discouraged, or
concerned if parts of it don’t make a lot of sense right now; much of it will become clearer
as the semester progresses. For now, just do the best you can to look for information that
you can use to answer the question(s) below.
Functions also introduce the concept of modularity, where a program can be broken up
into multiple smaller pieces; each of these modules contains one or more functions that can
be used to perform a small part of the overall task (and which can be reused by other
programs). Python includes a large library of modules, each of which includes useful pre
written functions that programmers can use in their own programs with the use of an
import statement. The “Python Standard Library” Web page, available at <https://
docs.python.org/3/library/index.html>, contains a full list of these “bundled” modules (the
list starts at the “Text Processing Services” bullet point and continues until the end of the
page).
In class to date, we’ve used or made reference to three of these modules: random,
string, and math. Choose TWO of the other modules listed on the “Python Standard
Library” page. For each module:
1. Identify the name of the module and briefly summarize what general purpose it serves.
2. Select THREE functions from this module. List each function’s name and briefly
describe what it does.
3. Give an example of a type of program (real or hypothetical) for which this module is
either essential or extremely useful.

C++ programming
To store the information about a city and its weather forecast, create a struct that holds the city's name (string), population (int), and a forecast array storing 7 string elements representing the city's weather in the next 7 days.
The program will then accept user input to enter the name and population of the city, then it accepts 7 string inputs to store into the forecast array.
Then the program will output the city's name, population, and forecast data.
Ex: If the inputs are:
Houston 2313000 sunny sunny sunny rainy thunderstorm sunny sunny
the function outputs:
Houston Population: 2313000 7 Day Forecast: Day 0: sunny Day 1: sunny Day 2: sunny Day 3: rainy Day 4: thunderstorm Day 5: sunny Day 6: sunny
Your program must name the struct "city" with name, population, and forecast as the corresponding member names!
Your program must define and call this function to output the city information:
void city_info(city c)
#include <iostream>
using namespace std;
/* Define your struct here */
/* Define your printing function here */
int main() {
/* Type your code here */
return 0;
}
