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

// Writing a C++ program for given scenario

// Making two variables to read first and last name

#include <iostream> //  Including standard Input/output stream

#include<string>    // Including string stream to use getline function

using namespace std;

// Main Function

int main()

{

   string inputString =" ";   // Variable for String input    

   cout<<"Enter full name :";    // Statement to get input

   getline(cin,inputString);               // using get line function to get input

/*

     Here getline function is used to get full line input. If you will use

     cin>> inputString than it will take input from stream until a space is

written, all the input after space will be discarded.

*/

// Taking length of the input

   int len = inputString.length();

// Index to get index of string where space is entered by the user

   int index =0;

// Variable to store first name

   char firstname[len];

/*

This for loop will start a counter (i) from end of string entered and will store all the characters in the variable declared above until space is hit

*/

  for(int i=0;i<len;i++){

       if(inputString[i]!=' ')

           firstname[i]=inputString[i];

       else{

           index = i;

           cout<<index<<endl;

           break;

       }

   }

// For loop to output last name

   for(int i=index+1;i<len;i++){

       cout<<inputString[i];

   }

// output the comma

   cout<<",";

// output the stored first number

   cout<<firstname<<endl;

   return 0;
