Signed vs. unsigned integers for lengths/counts http://stackoverflow.com/questions/10040884/signed-vs-unsigned-integers-for-lengths-counts to detect. With unsigned it would wrap around and become UINT_MAX . That makes it much harder to detect the error because you..
Efficient unsigned-to-signed cast avoiding implementation-defined behavior http://stackoverflow.com/questions/13150449/efficient-unsigned-to-signed-cast-avoiding-implementation-defined-behavior int as argument and returns an int congruent modulo UINT_MAX 1 to the argument. A first attempt might look like this int.. machines... If there is no signed int congruent modulo UINT_MAX 1 to the unsigned int let's say I want to throw an exception... is guaranteed by the standard to preserve the value modulo UINT_MAX 1. So the conditional does check exactly what I want and it..
Determining 32 vs 64 bit in C++ http://stackoverflow.com/questions/1505582/determining-32-vs-64-bit-in-c platform multiple compiler environment. #if ULONG_MAX UINT_MAX # define IS32BIT #else # define IS64BIT #endif #ifdef IS64BIT..
Implementing Dijkstra's Algorithm http://stackoverflow.com/questions/2899207/implementing-dijkstras-algorithm complication which is that any two vertices can have up to UINT_MAX different distances between them. Sorry. Infact the fact that..
Why does left shift operation invoke Undefined Behaviour when the left side operand has negative value? http://stackoverflow.com/questions/3784996/why-does-left-shift-operation-invoke-undefined-behaviour-when-the-left-side-oper E2 reduced modulo ULONG_MAX 1 if E1 has type unsigned long UINT_MAX 1 otherwise. Note the constants ULONG_MAXand UINT_MAXare defined.. long UINT_MAX 1 otherwise. Note the constants ULONG_MAXand UINT_MAXare defined in the header . That means int a 1 b 2 c c a b invokes..
Type Conversion/Casting Confusion in C++ http://stackoverflow.com/questions/4337306/type-conversion-casting-confusion-in-c result is the unsigned int value that is equal to i modulo UINT_MAX 1 and this rule is part of the language. So in this case the..
Testing for a maximum unsigned value http://stackoverflow.com/questions/4539469/testing-for-a-maximum-unsigned-value C others have already pointed out the limits.h header and UINT_MAX . Apparently solutions which are allowed to name the type are..
