The maximum value of a char is 255.
By adding 10 to that number you get 265.
Because that value is not a suitable value for a char it will do 265 % 256 resulting 9
That's why your result is 9

2The modulo reasoning is not quite correct. You don't use module 255 but module 256. – nm_tp Feb 20 '19 at 09:28

Oh yeah because there are 256 values possible (0 to 255). You're right – Darkpingouin Feb 20 '19 at 09:28
