How can I swap the first and last letters of the input stream in this program?

Hi, this is part of an assignment I was given in my introductory programming course. I simply need to know how I could swap the first and last letters of the input in this program:

int main()
{
    cout << "---------------------------------------------------------" << endl;
    cout << "              Letter Swapping Program" << endl;
    cout << "---------------------------------------------------------" << endl;
 
    string word;
    cout << "Please enter a word at least 3 letters long: ";
    cin >> word;
    cout << endl << endl;
 
    int wordLen = word.length();
    char firstLet = word.at(0);
    char lastLet = word.back();
 
    cout << "The length of " << word << "is " << wordLen << endl;
    cout << "The first and last letters of " << word << " are " << firstLet << " and " << lastLet << " respectively." << endl;
    cout << "If you swap the first and last letters of this word, you get: ";
 

By all means, I know this is a messy program and is not the most concise way to write it, but that's the extent of my knowledge so far in this class.

Thanks!

To swap, move one character to a temp variable while you load the other:

temp var = first letter;
first letter = last letter;
last letter = temp;

I'm trying to avoid writing the exact code so you can leanr this yourself.
