Rock, Paper, or Scissors Project

[Nalini1998]

Reference code was put at the comment below

Rock paper scissors Project is a classic two players game. Each player chooses either rock, paper, or scissors. The items are compared, and whichever player chooses the more powerful item wins.

The possible outcomes are:

• Rock destroys scissors.
• Scissors cut paper.
• Paper covers rock.
• If there’s a tie, then the game ends in a draw.

Our code will break the game into four parts:

1. Get the user’s choice.
2. Get the computer’s choice.
3. Compare the two choices and determine a winner.
4. Start the program and display the results.
