Since TileIndex is passed by value and value is the only instance variable, it's in essence nothing more than a cast which is just a compiler concept in this case. Descriptionchar x = 'a'; // int -> char, result unchanged unsigned char n = -123456; // target is unsigned, result is 192 (that is, -123456+483*256) signed char m = 123456; // target is signed, result is implementation-defined assert(sizeof(int) > -1); // assert fails: // operator > requests conversion of -1 to size_t, // target is unsigned, result is …You should always use the cast operator whenever there is a possibility of losing information, as in a conversion from int to unsigned int, for example. Explicit casts avoid compiler warnings, and also signpost your program’s type conversions for other programmers. alpha s3 key dimensions -1 is 0xFFFF, as unsigned int it looks very large (Two's complement for signed values). It looks to me as: "you mix" types of variables, you cast (even behind the scene) and you print as hex (but not as right signed value). Think about how -1/15 = 4369 can happen: as INT operation it should be zero (no fractional digits possible on an INT). 1 LikeThe rules for signed-to-unsigned conversion say that the value is reduced modulo UINT_MAX + 1, so -1 will convert to UINT_MAX (which is probably 0xffffffff or 4294967295 if unsigned int is 32 bits). You simply cannot assign a negative value to an object of an unsigned type. usta level 6 points Unsigned integers are used when we know that the value that we are storing will always be non-negative (zero or positive). Note: it is almost always the case that you could use a regular integer variable in place of an unsigned integer.You can convert an int to an unsigned int. The conversion is valid and well-defined. Since the value is negative, UINT_MAX + 1 is added to it so that the value is a valid unsigned quantity.We obtain.The question sounds confused.
