Answer:
Code:
import os # os module to create directory
event_file = open("event_details.txt", "r") # Getting event file
event_details = "" # event details to be stored
for row in event_file: # traversing through the event_file
event_details += row # appending event details
os.mkdir("./invitations") # make directory in the same parent directory
names = open("guest_list.txt", "r") # getting names of the people
for name in names: # traversing through names in guest_list file
name = name.replace('\n', '') # removing the ending '\n' from the name
invitation_msg = "Hi! " + name + ", You are heartly invited in the Ceremony.\nAt " + event_details # Generating the invitation message
file_name = '_'.join(name.split(' ')) # Spliting name in space and joining with the '_'
file_path = "./invitations/" + file_name + ".txt" # Generating each file path
invite_file = open(file_path, "w") # Creating the file for each name
invite_file.write(invitation_msg) # Write invitation to file

Explanation:
The following code is written in Python. It is a function called checkString that takes in a string as an argument and loops through each char in that string and checking to see if it is lowercase, uppercase, vowel, consonant, or punctuations. It adds 1 to the correct variable. At the end of the loop it prints out all of the variables. The picture below shows a test output with the string "Brainly, Question."
def checkString(word):
uppercase = 0
lowercase = 0
vowel = 0
consonants = 0
punctuation = 0
vowelArray = ['a', 'e', 'i', 'o','u', 'y' ]
consonantArray = ['b', 'c', 'd', 'f', 'g', 'h', 'j', 'k', 'l', 'm', 'n', 'p', 'q', 'r', 's', 't', 'v', 'w', 'x', 'y', 'z']
punctuationArray = ['.', '!', '?', ',', ';', '(', ')']
for char in word:
if char.isupper():
uppercase += 1
else:
lowercase += 1
if char.lower() in vowelArray:
vowel += 1
elif char.lower() in consonantArray:
consonants += 1
if char in punctuationArray:
punctuation += 1
print('Uppercase: ' + str(uppercase))
print('Lowercase: ' + str(lowercase))
print('Vowels: ' + str(vowel))
print('Consonants: ' + str(consonants))
print('Punctuations: ' + str(punctuation))

Here is the JAVA program:
import java.util.Scanner; //to accept input from user
public class Main { // class name
public static void main(String [] args) { // start of main method
Scanner input = new Scanner(System.in); // creates Scanner class object to take input from user
System.out.println("Please Enter the Cost of the Item: "); // prompts user to enter the cost of item
double itemCost = input.nextDouble(); //scans and reads the input value of item cost
System.out.println("Please Enter the Amount Paid: "); // prompts user to enter the amount paid
double amount = input.nextDouble(); //scans and reads the value of amount from user
int change = (int)(amount * 100 - itemCost * 100); //compute the remaining amount i.e. change
System.out.println("Change Owed: " + change / 100.0); // displays the owed change
int quarters = change / 25; // computes the value for quarters
change = change % 25; // compute the quarters remaining
int dimes = change / 10; // computes dimes
change = change % 10; // computes dimes remaining
int nickels = change / 5; // computes nickels
change = change % 5; // compute nickels remaining
int pennies = change; // computes pennies
System.out.println("Quarters: " + quarters); // displays computed value of quarters
System.out.println("Dimes: " + dimes); // displays value of dimes
System.out.println("Nickels: " + nickels); // displays value of nickels
System.out.println("Pennies: " + pennies); }} //displays value of pennies
Explanation:
I will explain the program with an examples.
Suppose the user enters 4.57 as cost of the item and 5.00 as amount paid. Then the program works as follows:
Change is computed as
change = (int)(amount * 100 - itemCost * 100);
This becomes;
change = (int)(5.00 * 100 - 4.57 * 100)
= 500 - 457
change = 43
Now the change owed is computed as:
change / 100.0 = 43/100.0 = 0.43
Hence change owed = 0.43
Next quarters are computed as:
quarters = change / 25;
This becomes:
quarters = 43/25
quarters = 1
Now the remaining is computed as:
change = change % 25;
This becomes:
change = 43 % 25;
change = 18
Next the dimes are computed from remaining value of change as:
dimes = change / 10;
dimes = 18 / 10
dimes = 1
Now the remaining is computed as:
change = change % 10;
This becomes:
change = 18 % 10
change = 8
Next the nickels are computed from remaining value of change as:
nickels = change / 5;
nickels = 8 / 5
nickels = 1
Now the remaining is computed as:
change = change % 5;
This becomes:
change = 8 % 5
change = 3
At last the pennies are computed as:
pennies = change;
pennies = 3
So the output of the entire program is:
Change Owed: 0.43 Quarters: 1 Dimes: 1 Nickels: 1 Pennies: 3
The screenshot of the output is attached.
