Declare a 4 x 5 array called N.

Using for loops, build a 2D array that is 4 x 5. The array should have the following values in each row and column as shown in the output below:

1 2 3 4 5
1 2 3 4 5
1 2 3 4 5
1 2 3 4 5

Write a subprogram called printlt to print the values in N. This subprogram should take one parameter, an array, and print the values in the format shown in the output above.

Call the subprogram to print the current values in the array (pass the array N in the function call).

Use another set of for loops to replace the current values in array N so that they reflect the new output below. Call the subprogram again to print the current values in the array, again passing the array in the function call.

1 1 1 1 1
2 2 2 2 2
3 3 3 3 3
4 4 4 4 4

Program:

# Array name will be "N".

# Start program

# Defining a function and taking input array

def printIt(ar):

# Using for loop to scan the rows as well as columns of array

for row in range(len(ar)):

for col in range(len(ar[0])):

# Printing the element of array

print(ar[row][col], end=" ")

print("")

# Passing the array N

N=[]

# Again using the loop

for r in range(4):

N.append([])

# Loop to control rows

for r in range(len(N)):

value=1

# Loop to control columns

for c in range(5):

N[r].append(value)

value=value + 1

# Calling the function

printIt(N)

print("")

newValue=1

# Value in row and column

for r in range (len(N)):

for c in range(len(N[0])):

# Assigning the values to the array

N[r][c] = newValue

newValue = newValue + 1

printf("Height: %d \n", height);

printf("Length: %d \n", length);

You are responsible for a rail convoy of goods consisting of several boxcars. You start the train and after a few minutes you realize that some boxcars are overloaded and weigh too heavily on the rails while others are dangerously light. So you decide to stop the train and spread the weight more evenly so that all the boxcars have exactly the same weight (without changing the total weight). For that you write a program which helps you in the distribution of the weight.
Your program should first read the number of cars to be weighed (integer) followed by the weights of the cars (doubles). Then your program should calculate and display how much weight to add or subtract from each car such that every car has the same weight. The total weight of all of the cars should not change. These additions and subtractions of weights should be displayed with one decimal place. You may assume that there are no more than 50 boxcars.
Example 1
In this example, there are 5 boxcars with different weights summing to 110.0. The ouput shows that we are modifying all the boxcars so that they each carry a weight of 22.0 (which makes a total of 110.0 for the entire train). So we remove 18.0 for the first boxcar, we add 10.0 for the second, we add 2.0 for the third, etc.
Input

40.0
12.0
20.0
5. 33.

Output
- 18.0
10.0
2.0

-11.0

Answers

Answer:

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; }

Create a public class called Exceptioner that provides one static method exceptionable. exceptionable accepts a single int as a parameter. You should assert that the int is between 0 and 3, inclusive.
If the int is 0, you should return an IllegalStateException. If it's 1, you should return a NullPointerException. If it's 2, you should return a ArithmeticException. And if it's 3, you should return a IllegalArgumentException.

Answers

Answer:

// Begin class declaration

public class Exceptioner {

// Define the exceptionable method

public static void exceptionable(int number){

//check if number is 0.

if(number == 0) {

//if it is 0, return an IllegalStateException

throw new IllegalStateException("number is 0");

}

//check if number is 1

else if(number == 1) {

//if it is 1, return a NullPointerException

throw new NullPointerException("number is 1");

}

//check if number is 2

else if(number == 2) {

//if it is 2, return an ArithmeticException

throw new ArithmeticException("number is 2");

}

//check if number is 3

else if(number == 3) {

//if it is 3, return an IllegalArgumentException

throw new IllegalArgumentException("number is 3");

}

Sample Output:

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.

How does a systemic change happen?

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.

Why is systems change important?

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.

You plan to make a delicious meal and want to take the money you need to buy the ingredients. Fortunately you know in advance the price per pound of each ingredient as well as the exact amount you need. The program should read in the number of ingredients (up to a maximum of 10 ingredients), then for each ingredient the price per pound. Finally your program should read the weight necessary for the recipe (for each ingredient in the same order). Your program should calculate the total cost of these purchases, then display it with 6 decimal places.

Example There are 4 ingredients and they all have a different price per pound: 9.90, 5.50, 12.0, and 15.0. You must take 0.25 lbs of the first, 1.5 lbs of the second, 0.3 lbs of the third and 1 lb of the fourth. It will cost exactly $29.325000.

Answers

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)

The program uses recursion to determine its operations and outputs.

It initially gets the following as its input from the main method

a= 1; r = 2; counter = 0

Its operation goes thus:

val = a*r; 1 * 2 = 2

Print val; Prints 2

if (counter > 4) { System.out.print("End"); } : Not true
