Thread: reversing string not working

Code:

//function declaration
string stringReverse(string arg)
{
       string word = arg;
       
       for(int i = word.length(); i >= 0; i--)
               {
                   char temp;
                   
                   word[0] = temp;
                   word[0] = word[i];
                   word[i] = temp;

               }
               
       
       return word;

}

If what I think I'm doing is correct, this should reverse a string, yes?

When I pass soemthing to the function, and then output the result - only blank spaces appear on the screen. Am I going out of bounds? What am I doing wrong here?
