Game-Tracker Assignment
For this version of the Game-tracker program, you will declare 10 objects of your game tracking class. Then create a loop that will allow the user to continue write your C++ assignment program to add new games and to see and adjust their scores until they indicate they are done. (Hint: this is indeterministic). You should present a menu to the user that lets them pick the action they want to do inside the loop at the current time and use a switch to react to the choice. Something like:
Please select a choice:
- Enter the new game
- Update times played or high score
- See all game stats
- Quit.
You will need to search for the game needed (in another loop inside the main loop) for option 2 above. Inside of the main loop, when the user wants to enter a new game, which they must do before seeing any scores, give the user the ability to enter up to 10 games and their initial scores (potentially deterministic). After the first game is entered, the other menu options become valid and new games up to 10 may be entered at any time. Your output should show the user entering incorrect values and the error checking you are doing, as in the last program as well as the entering of 3 or more games (maximum 10) and after games are entered, the checking and updating of score information and the number of times played.
