Explanation

Random Number Generation:
- srand(static_cast<unsigned int>(time(0))); seeds the random number generator to ensure the computer’s choice is different each time the game is played.
getComputerChoice Function:
- This function generates a random number between 0 and 2, mapping each number to one of the choices: “Rock”, “Paper”, or “Scissors”. This simulates the computer’s move in the game.
determineWinner Function:
- This function compares the player’s choice with the computer’s choice to determine the winner based on the rules of Rock, Paper, Scissors:
  - Rock beats Scissors
  - Paper beats Rock
  - Scissors beats Paper
- If both choices are the same, it’s a tie.
Player Input:
- The player is prompted to enter their choice, which is then processed to ensure the first letter is capitalized, making it easier to compare with the computer’s choice.
Main Function:
- The main() function handles the game loop:
  - It gets the player’s choice.
  - It determines the computer’s choice.
  - It prints the computer’s choice.
  - It determines and displays the winner.
