Many documents use a specific format for a person's name. write a program whose input is: firstname middlename lastname and whose output is: lastname, firstname middleinitial. ex: if the input is: pat silly doe the output is: formatted name: doe, pat s. if the input has the form firstname lastname, the output is lastname, firstname ex: if the input is: julia clark the output is: formatted name: clark, julia if the input has any other form, then the output should be the input does not have the correct form

name = input(" Enter your Name:")

br = name.split()

def split(word):  

return list(word)  

word = br[1]

print(br[2],", ",br[0]," ",word[0])

Explanation:

The Programming Language used is python.

The function used is called a split function, it allows the splitting of a string into a list of words and is the best method to accomplish this particular task.

Line 1:

name = input(" Enter your Name:")

initializes the string and prompts the person to input a name

Line 2:

br = name.split()

uses split()  to break the string up into a list of words. with each slot having its unique identifier (index number) starting from 0.

Line 3, 4, 5 :

def split(word):  

return list(word)  

word = br[1]

- if the input as in your example is "Pat Silly Doe" what happens is that "Pat Silly Doe" is broken up into a list.

-we now have [Pat, Silly, Doe] and each of the elements in the list have their unique index.

Pat-0

Silly-1

Doe-2

Silly is split into individual characters [s,i,l,l,y]

Line 6:

print(br[2]," ",br[0]," ",word[0])

This prints out the names in the new format of:

br[2] --> Doe

br[0] --> Pat

word[0] --> s

Doe, Pat S

The code is given below in Java with appropriate comments

Explanation:

//declaring the imports

import java.util.Scanner;

//class FormatName

public class FormatName {

    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);

       //inputing the names

       System.out.print("Enter your name (first middle last): ");

       String fullName = scanner.nextLine();

       String[] names = fullName.split("\\s+");

//applying the formatting

       if (names.length == 2) {

           System.out.println("Formatted Name: " + names[1] + ", " + names[0]);

       } else if (names.length == 3) {

           System.out.println("Formatted Name: " + names[2] + ", " + names[0] + " " + names[1].charAt(0) + ".");

       } else {

           System.out.println("The input does not have correct form");

       }

   }

}

well you didnt give us any options it looks like so im going to go with because cash cant be traced.
