Finally made it :slight_smile: but it would be great to have feedback on how can I make it shorter without duplicating the IF statements too much

I don’t know C++, but I do know C.
If I were you, I would use the users input as an array index, and just print what’s in the array, like this:

OPTIONS = ["", "Rock\n", "Paper\n", "Scissors\n", "Lizard\n", "Spock\n"];
std::cout << OPTIONS[user];
std::cout << OPTIONS[computer];

Also, if you have an 2D array, like this:

COMBAT = [[0, -1, 1, 1, -1],
                    [1, 0, -1, -1, 1],
                    [-1, 1, 0, 1, -1],
                    [-1, 1, -1, 0, 1],
                    [1, -1, 1, -1, 0]];

You can just check the winner like this:

if (COMBAT[user][computer] == 1)
{
    //User Wins!
}
else if (COMBAT[user][computer] == -1)
{
    //Computer Wins!
}
else
{
    //Tie!
}

You see, if you have it like this, you could even add more options. you would just need to add them to the selection part and the 2D array!

Also, by the by, you can put code into a post with the </> symbol in the editor.

Thank you soo much :slight_smile: I will give a go

Oh, by the way, you should subtract 1 from the user and computer values before you use them as an index.

Also, do you have a link you could share of the program?

Hi Dyenamite,
Sorry for the delay, how do you setup a custom program to share with the community?

  1. Create a GitHub Account
  2. Download GitHub Desktop
  3. Create a public Repository, with a lisence!
  4. Put your file(s) into the folder you’ve chosen
  5. Publish your repository
  6. Now you can send folks the URL, which allows them to download the program
