[C++] Issue with my average fonction...

Question

hello everyone,
I share my mini games from my computer( one of my first code, translated from french) because i have a issue with my average fonction (step 4) and the score on the second play.

i try to convert a average score of victory to a percentage but on the second victory, my "for" loop a another time and cause issue:
expected result : 100%
result : 150%
clue: one of my variable (averageWin if i remember correctly ) in average fonction become a 3,5

Answer 1

After the first win, scoreWin is { 1.0 }. The loop executes once, and averageWin is now (averageWin + 1.0) / 1 = 1.0. So, you get 100%.

After the second win, scoreWin is { 1.0, 1.0 }. The loop executes twice, and averageWin is now (averageWin + 1.0 + 1.0) / 2 = 1.5. So, you get 150%.

As you can see, Nofel's suggestion is correct: You need to reset averageWin back to 0.0 at the start of every new game.

Answer 2

maybe you should reset your averagewin variable too?
