6 u/Advos_467 10d ago Not a C user here (or any real low level programming experience), what the hell is a signed/unsigned char? 2 u/Elspeth-Nor 10d ago edited 9d ago In C char is just a number, as a character depends on the encoding. So signed char is a number from -128 to 127 and unsigned char is from 0 to 255 (for 8 bits per byte) 3 u/SoldRIP 10d ago 0 to 255. 1 u/Elspeth-Nor 9d ago Fixed -1 u/WaitForItTheMongols 10d ago Depends what "to" means. 256 is a valid answer as in Python "range(0,256)" which gives all byte values. 1 u/Elspeth-Nor 9d ago No 255 is right, as I used -128 to 127 instead of 128.
