Write a function

string middle(string str)
that returns a string containing the middle character in str if the length of str is odd, or the two middle characters if the length is even. For example, middle("middle") returns "dd".

I'm not getting the correct output. What am I doing incorrectly?

O#include <iostream>

using namespace std;
string middle(string str);
Bint main()
string userInput;
cout <« "Enter a word: ";
cin >> userInput;
middle(userInput);
cout << userInput;
astring middle(string str)
{
string middleCharacters;
if (str.length() % 2 :
0)
==
{
middleCharacters
str.substr((str.length() / 2) + 1);
==
cout <«< middleCharacters;
if (str.length() % 2 != 0)
{
middleCharacters
str.substr(str.length() / 2);
==
cout << middleCharacters;
return middleCharacters;
