Write a program that demonstrates how various exceptions are caught with catch(Exception exception). This time define classes ExceptionA (which inherits from class Exception) and ExceptionB (which inherits from class ExceptionA). In your program, create try blocks that throw exceptions of types ExceptionA, ExceptionB, NullPointerException and IOException. All exceptions should be caught with catch blocks specifying type Exception.

Answer:

In Python:

prices = []

pounds = []

print("Enter 0 to stop input")

for i in range(10):

   pr = float(input("P rice: "+str(i+1)+": "))

   pd = float(input("Pound: "+str(i+1)+": "))

   if pr != 0 and pd != 0:

       prices.append(pr)

       pounds.append(pd)

   else:

       break

amount = 0

for i in range(len(pounds)):

   amount+= (pounds[i]*prices[i])

print("Amount: $",amount)

Explanation:

These initialize the prices and pounds lists

prices = []

pounds = []

This prompts the user to enter up to 10 items of press 0 to quit

print("Enter 0 to stop input")

This iterates through all inputs

for i in range(10):

This gets the price of each item

   pr = float(input("P rice: "+str(i+1)+": "))

This gets the pound of each item

   pd = float(input("Pound: "+str(i+1)+": "))

If price and pound are not 0

   if pr != 0 and pd != 0:

The inputs are appended to their respective lists

       prices.append(pr)

       pounds.append(pd)

If otherwise, the loop is exited

   else:

       break

This initializes total to 0

amount = 0

This iterates through all inputs

for i in range(len(pounds)):

This multiplies each pound and each price and sum them up

   amount+= (pounds[i]*prices[i])

The total is then printed

print("Amount: $",amount)

Answer:

Follows are code to the given question:

def countdown_trigger(begin):#defining a method countdown_trigger that accepts a parameter

   i = begin#defining variable that holds parameter value

   while i >= 0:#defining while loop that check i value greater than equal to0

       print(i)#print i value

       i -= 2  # decreasing i value by 2  

print(countdown_trigger(2))#calling method

Output:

2

0

None

Explanation:

In this code, a method "countdown_trigger" is declared, that accepts "begin" variable value in its parameters, and inside the method "i" declared, that holds parameters values.

By using a while loop, that checks "i" value which is greater than equal to 0, and prints "value" by decreasing a value by 2.

Explanation:

The following code is written in Python, it asks the user for the number of minutes worked. Divides that into hours and minutes, saves the values into separate variables, and then prints the correct statement using those values. Output can be seen in the attached image below.

import math

class HoursAndMinutes:

   min = input("Enter number of minutes worked: ")

   hours = math.floor(int(min) / 60)

   minutes = (int(min) % 60)

   print(str(hours) + " hours and " + str(minutes) + " minutes")

The effect when one part of a system changes C. The open-loop system becomes a closed-loop system.

Systemic change is generally understood to require adjustments or transformations in the policies, practices, power dynamics, social norms or mindsets that underlie the societal issue at stake. It often involves the collaboration of a diverse set of players and can take place on a local, national or global level.

All systems organize individual pieces into some sort of interrelated whole. Put simply, systemic change occurs when change reaches all or most parts of a system, thus affecting the general behavior of the entire system.

A systems-change approach is more appropriate for problems that are complex, unpredictable, and context-dependent. For example, the challenge of inadequate access to educational opportunities for children from low-income neighborhoods cannot be addressed with a straightforward, logistical fix.

Explanation:

The correct answer is - once per month

Reason -

Probability of 1 failure of 1000 hard disk = 750,000/1000 = 750 hrs

So,

750/24 = 31.25 days

⇒ approximately one in a month.

The program in C++ is as follows:

#include <iostream>

#include <iomanip>

using namespace std;

int main(){

   int cars;

   cin>>cars;

   double weights[cars];

   double total = 0;

   for(int i = 0; i<cars;i++){

       cin>>weights[i];

       total+=weights[i];    }

   double avg = total/cars;

   for(int i = 0; i<cars;i++){

       cout<<fixed<<setprecision(1)<<avg-weights[i]<<endl;    }

   return 0;

}

Explanation:

This declares the number of cars as integers

   int cars;

This gets input for the number of cars

   cin>>cars;

This declares the weight of the cars as an array of double datatype

   double weights[cars];

This initializes the total weights to 0

   double total = 0;

This iterates through the number of cars

   for(int i = 0; i<cars;i++){

This gets input for each weight

       cin>>weights[i];

This adds up the total weight

       total+=weights[i];    }

This calculates the average weights

   double avg = total/cars;

This iterates through the number of cars

   for(int i = 0; i<cars;i++){

This prints how much weight to be added or subtracted

       cout<<fixed<<setprecision(1)<<avg-weights[i]<<endl;    }
