   // Your code goes here

}

Explanation / Answer

Complte program code:

#include <iostream>
#include <string>
using std::cout;
using std::endl;
using std::string;
void reverseString(string in_str);
int main()
{
string str1 = "Hello World!";
string str2 = "racecar"
string str3 = "2106AD";
string str4 = "a man a plan a canal-panama";
string str5 = " ";
  
reverseString(str1);
cout << endl;
reverseString(str2);
cout << endl;
reverseString(str3);
cout << endl;
reverseString(str4);
cout << endl;
reverseString(str5);
return 0;
}
void reverseString(string in_str)
{
if (in_str.length() == 1) {
return in_str;
}else{
