Write a program that reads a list of words. Then, the program outputs those words and their frequencies. The input begins with a

Answer:
The following are the program to the given question:
import java.util.*;//import package for user input
public class Make //define class Make
{
public static void main(String[] ask) //define a main method
{
Scanner obx = new Scanner(System.in); //declare the Scanner class object
int size=obx.nextInt(); //get the size of the array from the user
int a[]=new int[size]; //declare an integer array with given size
String word[]=new String[size]; //declare a string array with given size
for(int i=0;i<size;i++) //set the for loop
word[i]=obx.next(); //get string input from the user
for(int i=0;i<size;i++) //iterates with the array, increase the count
{
for(int j=0;j<size;j++) //defining a loop to check value
{
if(word[i].equals(word[j])) //use if to check that elements of words
a[i]++;//increamenting array size
}
}
System.out.print("\n"); //use print for break line
for(int i=0;i<size;i++)//set for loop to print the following result
System.out.println(word[i]+" "+a[i]);//print value
}
}
Output:
Please find the attachment file.
Explanation:
- First, establish the predefined package required and instead define the main class and define the main method within the class and method.
- Declare the scanner class object and receive an object size in the 'size' variable thru the array.
- Next create two arrays, the integer type "a" with both the input size given and the string type "word" with the input size supplied.
- Define the loop for which string array elements are acquired and set two to again for loop, which increases with loop iteration the integer data type array by one.
- Lastly, set the loop for which this result is printed.

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.
