Project 6 - RPS ✂️

Lets make a game of rock paper scissors for two players.

---

Tasks 🎯

Ask and store the first player’s choice. Assume their choice is a single word no longer than 15 characters.

> Player 1 enter "rock", "paper", or "scissors":
> rock

Solution ✅

#include <stdio.h>

int main() {
    char player_one_choice[16] = "";

    printf("Player 1 enter \"rock\", \"paper\", or \"scissors\":\n");
    scanf("%s", player_one_choice);

    return 0;
}

Ask and store the second player’s choice. Assume their choice is a single word no longer than 15 characters.

> Player 1 enter "rock", "paper", or "scissors":
> rock
> Player 2 enter "rock", "paper", or "scissors":
> scissors

Solution ✅

#include <stdio.h>

int main() {
    char player_one_choice[16] = "";

    printf("Player 1 enter \"rock\", \"paper\", or \"scissors\":\n");
    scanf("%s", player_one_choice);


    char player_two_choice[16] = "";

    printf("Player 2 enter \"rock\", \"paper\", or \"scissors\":\n");
    scanf("%s", player_two_choice);

    return 0;
}

Using if statements, print “Tie” if there is a tie, otherwise print who won.

> Player 1 enter "rock", "paper", or "scissors":
> rock
> Player 2 enter "rock", "paper", or "scissors":
> rock
> Tie

> Player 1 enter "rock", "paper", or "scissors":
> rock
> Player 2 enter "rock", "paper", or "scissors":
> scissors
> Player 1 wins!

> Player 1 enter "rock", "paper", or "scissors":
> rock
> Player 2 enter "rock", "paper", or "scissors":
> paper
> Player 2 wins!

Solution ✅

#include <stdio.h>
#include <string.h>

int main() {
    char player_one_choice[16] = "";

    printf("Player 1 enter \"rock\", \"paper\", or \"scissors\":\n");
    scanf("%s", player_one_choice);


    char player_two_choice[16] = "";

    printf("Player 2 enter \"rock\", \"paper\", or \"scissors\":\n");
    scanf("%s", player_two_choice);

    if (strcmp(player_one_choice, player_two_choice) == 0) {
        printf("Tie\n");
    } else if ((strcmp(player_one_choice, "rock") == 0 && strcmp(player_two_choice, "scissors") == 0) ||
        (strcmp(player_one_choice, "scissors") == 0 && strcmp(player_two_choice, "paper") == 0) ||
        (strcmp(player_one_choice, "paper") == 0 && strcmp(player_two_choice, "rock") == 0)
    ) {
        printf("Player 1 wins!\n");
    } else {
        printf("Player 2 wins!\n");
    }

    return 0;
}
