This program implements a tennis scoreboard simulation with detailed scorekeeping and real-time updates for each point, game, and set. It uses the following structure and logic:

1. Score Tracking:

   • Points, games, and sets are tracked for each player (Team A and Team B).

2. Rules Implementation:

   • Tennis scoring rules are implemented:
     • A game is won if a player scores at least 4 points and leads by 2.
     • A set is won if a player wins at least 6 games and leads by 2.
     • A match is won if a player wins 3 sets.

3. Dynamic Serving:

   • The serving alternates between teams after each game.

4. Real-Time Results:

   • The scoreboard updates after every point, reflecting the current game and set scores.

1. Variables:

   • gamesA, gamesB: Games won by Team A and B in the current set.
   • pointsA, pointsB: Points scored by each team in the current game.
   • setsA, setsB: Total sets won by each team.
   • service: Keeps track of who serves (-1 for Team A, +1 for Team B).
   • counter: Tracks the number of completed sets.

2. results() Function:

   • Displays the current score, including points, games, and sets.
   • Handles special cases like "Deuce" and "Advantage."

3. pointsCalc() Function:

   • Maps the number of points to tennis scoring terminology (15, 30, 40).

4. main() Function:

   • Continuously reads input for which team scores (A or B).
   • Updates points, games, and sets based on the scoring rules.
   • Checks for game, set, and match winners after each point.
   • Calls results() to display the current state of the scoreboard.

1. Input Handling:

   • Current implementation reads characters without handling invalid inputs.
   • Add validation for inputs to ensure only 'A' or 'B' is accepted.

2. Output Formatting:

   • Avoid redundant %d placeholders for results() calls. Replace with proper formatting.

3. End Game Logic:

   • Automatically stop the game after determining the match winner to prevent further input.

4. Refactor Code:

   • Extract repetitive logic into reusable functions for better readability and maintainability.

5. Edge Cases:

   • Consider scenarios like tiebreaks for sets that reach 6-6.

6. User Experience:

   • Add clear instructions and better formatting for easier understanding.
