    return rand() % 3; // Returns 0, 1, or 2 for Rock, Paper, or Scissors
}

// Function to determine the winner
void determineWinner(int playerChoice, int computerChoice) {
    if (playerChoice == computerChoice) {
        printf("It's a tie!\n");
    } else if ((playerChoice == 0 && computerChoice == 2) ||
               (playerChoice == 1 && computerChoice == 0) ||
               (playerChoice == 2 && computerChoice == 1)) {
        printf("You win!\n");
    } else {
        printf("Computer wins!\n");
    }
}

int main() {
    int playerChoice, computerChoice;
    
    // Seed the random number generator
    srand(time(NULL));
    
    // Display game options to the player
    printf("Welcome to Rock, Paper, Scissors!\n");
    printf("Choose your option:\n");
    printf("0. Rock\n");
    printf("1. Paper\n");
    printf("2. Scissors\n");
    
    // Take player's choice
    printf("Enter your choice (0/1/2): ");
    scanf("%d", &playerChoice);
    
    // Ensure valid input
    if (playerChoice < 0 || playerChoice > 2) {
        printf("Invalid choice. Please choose 0, 1, or 2.\n");
        return 1;
    }
    
    // Get computer's choice
    computerChoice = getComputerChoice();
    
    // Display choices
    printf("You chose: ");
    if (playerChoice == 0) printf("Rock\n");
    else if (playerChoice == 1) printf("Paper\n");
    else if (playerChoice == 2) printf("Scissors\n");
    
    printf("Computer chose: ");
    if (computerChoice == 0) printf("Rock\n");
    else if (computerChoice == 1) printf("Paper\n");
    else if (computerChoice == 2) printf("Scissors\n");
    
    // Determine the winner
    determineWinner(playerChoice, computerChoice);
    
    return 0;
}

Explanation of the Program Structure

This program is a simple implementation of the Rock, Paper, Scissors game in C. Let’s break it down:

• getComputerChoice(): This function generates a random number between 0 and 2 using the rand() function. It simulates the computer’s choice of Rock, Paper, or Scissors.
• determineWinner(): This function compares the player’s choice with the computer’s choice and prints the outcome, whether it’s a tie, a win, or a loss.
• main(): This is the entry point of the program. It displays the available choices to the player, takes the player’s input, generates the computer’s choice, and then determines and displays the winner.

How to Run the Program

1. Open your C programming environment or IDE.
2. Copy the code provided and paste it into a new C file (e.g., rock_paper_scissors.c).
3. Compile the program using a C compiler (e.g., gcc rock_paper_scissors.c -o rock_paper_scissors).
4. Run the compiled program (e.g., ./rock_paper_scissors on Unix-based systems or rock_paper_scissors.exe on Windows).
5. Enjoy the game! Choose between Rock, Paper, or Scissors and see if you can beat the computer!
