The power of STL for my entertainment:

#include <iostream>
#include <string>
#include <algorithm>

using namespace std;

int main()
{
  string TheWord("I am a string!");
  reverse(TheWord.begin(), TheWord.end());
  cout<<TheWord<<endl;
  
  return 0;
}

#include <iostream>
#include <string>
#include <algorithm>

using namespace std;

int main()
{
  string TheWord("I am a string!");
  string Reversed(TheWord); //sizing
  reverse_copy(TheWord.begin(), TheWord.end(), Reversed.begin());
  cout<<Reversed<<endl;
  
  return 0;
}

Many variations to this code can be made. And all of them require an IQ of any one-cell organism
