Rock paper scissors Spock lizard

You must have played Rock paper scissors in your childhood. In this problem, we will implement a variation with Spock and lizard shapes which we refer to as RPSSL.

RPSSL shapes are resolved as in Fig. 13.

🤖 Agent won!

Expectations:

• has an entry menu

• the agent can play randomly

• shows score after each shape comparison

• can handle wrong input both in the menu and gameplay, e.g., by showing an error message

  • in case you know EOF: you don’t have to handle it

• if a player reaches the WINNING_SCORE

  • then this player wins

  • the program exits.

Important

Applies to all problems: you may override expectations and be creative, as long as your design decisions make sense to you and you can explain it.

Activity 21 (Flowchart v1 – overview)

Draw a flowchart for the problem. First focus on the menu and leave the details of a game round (until someone wins) out. In other words, represent a game round with a single process.

Activity 22 (Needed language syntax)

Break the flowchart down into language components. Which syntax from C can we use?
