What happens when casting between these two in relation to the termination character? In C99 Objective-C.
I assume that a char is 8 bits on your system in this answer.
If your architecture uses
unsigned charaschartype then absolutely nothing will happen.If your architecture uses
signed charaschartype then negative values of char will wrap around causing possibly unexpected results. This however will never happen to the termination null character.Please note, by “casting” nothing really happens, you just tell the compiler to interpret a certain location in the memory differently. This difference in interpretation would create the actual (side)effects of the cast.
