Answer:
1st question:
Use the variables k, d, and s so that they can read three different values from standard input an integer, a float, and a string respectively. On one line, print these variables in reverse order with exactly one space in between each. On a second line, print them in the original order with one space in between them.
Solution:
In Python:
k = input() #prompts user to input value of k i.e. integer value
d = input() #prompts user to input value of d i.e. float value
s = input() #prompts user to input value of s i.e. a string
print (s, d, k) #displays these variable values in reverse order
print (k, d, s)#displays these variable values in original order
In C++:
#include <iostream> // to use input output functions
using namespace std; //to identify objects like cin cout
int main() { //start of main function
int k; //declare int type variable to store an integer value
float d; // declare float type variable to store a float value
string s; // declare string type variable to store an integer value
cin >> k >> d >> s; //reads the value of k, d and s
cout << s << " " << d << " " << k << endl; //displays these variables values in reverse order
cout << k << " " << d << " " << s << endl; } // displays these variable values in original order

2nd question:
You would like the user of a program to enter a customer’s last name. Write a statement that asks user "Last Name:" and assigns input to a string variable called last_name.
Solution:
In Python:
last_name = input("Last Name:")
# input function is used to accept input from user and assign the input value to last_name variable
In C++:
string last_name; //declares a string type variable named last_name
cout<<"Last Name: "; // prompts user to enter last name by displaying this message Last Name:
cin>>last_name; // reads and assigns the input value to string variable last_name
The programs alongwith their outputs are attached.
Answer:
# the user is prompt to enter first value
user_val1 = int(input("Enter first value: "))
# the user is prompt to enter second value
user_val2 = int(input("Enter second value: "))
# max_magnitude function is defined
# it takes two parameters
def max_magnitude(user_val1, user_val2):
# if statement to compare the values
# it compare the absolute value of each
if(abs(user_val2) > abs(user_val1)):
return user_val2
elif (abs(user_val1) > abs(user_val2)):
return user_val1
# max_magnitude is called with the
# inputted value as parameter
print(max_magnitude(user_val1, user_val2))
Explanation:
The code is written in Python and well commented. A sample image of program output is attached.
Answer:
Explanation:
The diagrams attached to the questions are shown in the first and the second image below. The first image shows the code and the second image shows the error that appears at the moment of running it.
To answer that ; We will notice that the error in the second image is what it says; what happened is that the individual subject performing this action is trying to to open the file called "h.txt", but the python interpreter is unable to find the file. The individual subject will need to have h.txt inside your current working directory for python to open it.
From the third image attached ; I have careful attached an image that illustrate how you can add the file by going to file → open (right from your jupyter notebook). Afterwards you can either upload the file, or create a new text file and paste the contents on it as displayed in the fourth image attached in the diagram below.
