Description

The purpose of this challenge is to use the WHILE loop with other conditional statements (IF, IF-ELSE, etc). This exercise simulates the scoring of a tiebreak game in a tennis match.

Tiebreak Scoring in Tennis

Both players start at 0
Whoever wins a point gets a point added to their tally
Scores are typically displayed separated by a dash
The tiebreak will continue until one of the players gets a score of 7 or higher, while leading the other player with at least a difference of 2. Examples below:
- 7-0 — This tiebreak is over. One player reached 7, the other got 0. The difference between their scores is 7
- 7-5 — This tiebreak is over. One player reached 7, the other got 5. The difference between their scores is 2
- 7-6 — This tiebreak must continue to be played. One player reached 7, the other got 6. The difference between their scores is only 1 (must be at least 2)
- 9-9 — This tiebreak must continue to be played. One player reached 9, the other also got 9. The difference between their scores is 0 (must be at least 2)
- 6-4 — This tiebreak is still in progress. Neither player has reached 7
After every 6 points, the players must switch ends on the tennis court. Examples below:
- 3-3 — Total is 6. Players must switch ends
- 2-4 — Total is 6. Players must switch ends
- 6-6 — Total is 12. Players must switch ends.
- 2-5 — Total is 7. Players stay on their current ends

Requirements

Declare two strings: player1, player2
Declare three integers: score1, score2 and input
Declare a boolean variable: gameover. Initialize this to false.
Ask the user to enter the name a tennis player. Receive this input into player1. Use the code below which allows you to enter a string that contains a space (such as a full name)
```
cout << "Enter Player 1: ";
getline(cin, player1);
```
Do the same thing for player2
To display the score, write the code below. The setw(xx) call is used for formatting text output. For example, if xx is 20, this displays the next piece of data aligned within 20 spaces. The length() property of a string will provide the number of characters in the string. For example if player1 contained “Serena” then player1.length() gives 6 (the number of characters in Serena)
```
 cout << player1 << setw(25 - player1.length()) << score1 << endl;
 cout << player2 << setw(25 - player2.length()) << score2 << endl;
```
Add #include <iomanip> below the other #include at the top of the code
Write a while loop block that will continue as long as gameover is not true. (Remember that this was initialized to false in Step 3). Inside the while loop, do the following:
1. Ask the user “Who wins the next point (Player 1 or 2)?”. Use the input variable to receive the user’s response.
2. Increment score1 if Player 1 wins the next point. Do the same for score2 accordingly.
3. Display the score again by writing the same code from step 6
4. Now the tricky part. Set gameover to true if either of Player 1 or Player 2 has reached a score of 7, and is ahead by at least 2 points.
5. If the game is not over (gameover is not true) and the total number of points played is divisible by 6, display a message “Players must switch ends before next point” This essentially covers the requirement of switching ends every six points.
Display who wins (See sample interaction for how to format the final information)

DO NOT USE

You may not use any user-defined functions, or any other loops other than WHILE.
