Challenge activity 2.15.1: reading and outputting strings. write a program that reads a person's first and last names, separated by a space. then the program outputs last name, comma, first name. end with newline. example output if the input is: maya jones jones, maya 1 2 3 4 5 6 7 8 9 10 11 12 #include #include using namespace std; int main() { string firstname; string lastname; /* your solution goes here */ return 0; } 1 test passed all tests passed run

#include <iostream>

using namespace std;

int main()

{

   string Fname, Lname;

   cout << "Please Enter your first name " <<"Please Enter Your Last Name" <<endl;

   cin>>Fname>>Lname;

   cout<<Lname<<", "<<Fname<<endl;

   return 0;

}

Explanation:

This program is written in C++ programming Language. Firstly two string variables are declared these are Fname and Lname for first and last name respectively. C++ cout statement is used to prompt user for inputs and the cin statement is used to save the inputs in the respective variables. Using the cout operators (<<) the output is formatted as required by the question

import java.util.Scanner;

public class SpaceReplace {

  public static void main(String[] args) {

     Scanner scnr = new Scanner(System.in);

     String firstName;

     String lastName;

     firstName = scnr.next();

     lastName = scnr.next();

     System.out.println (lastName + ", " + firstName);

  }

}
