C błędy kompilacji: zbłąkane '\ 200' w programie i oczekiwane ')' przed stałą numeryczną

Question

Skopiowałem ten program i mam problem z funkcją void downFrequency (chyba). To jest dla Arduino Uno. Oto błędy kompilatora: kompilowania 'MY_dds' dla 'Arduino Uno'

Answer 1

pan jakoś skończyło się na "En kreska" znaków, zamiast normalne znaki minus, w funkcji downFrequency.

Upewnij się, że edytujesz za pomocą edytora tekstu, a nie edytora tekstu; i dla każdego z nich:

toFrequency = (toFrequency – 1); 
         ^

usunięcie zaznaczonej litery i ponowne wpisanie jej jako zwykłego znaku minus.

(Jeśli jesteś zainteresowany w krwawych szczegółów, postać „kreska” jest Unicode 2013, kodowane w UTF-8 bajtów z trzech wartości ósemkowej 324,200,223, dlatego widzisz te liczby w komunikatach o błędach.)

Answer 2

prawdopodobnie twój podwójne symbole cudzysłów (") były błędne. Proszę sprawdzić, czy są one rzeczywiście ", a nie ”.

Answer 3

kompilator narzeka, że ​​są znaki spoza ASCII w pliku źródłowym.

Mój ósemkowy fu jest zardzewiały, ale dla mnie wygląda jak UTF-8. 342 200 223 to E2 80 93, który jest Unicode "EN DASH". Kod ten otrzymał odszukanie znaku minus przez edytora tekstu ze stopniem kosmetologii.
