i trying understand difference of vocabulary used in c++ language between digits , bits in : char_bit; std::numeric_limits<char>::digits; is there conceptual difference? maybe weird architectures? if so, called result of operator[] of std::bitset . give access bit or digit? and current documentation of boost not help: cppint provides code digits documentation mention bits (this problem documentation, don't know whether text or code more recent.) from this std::numeric_limits::digits reference : the value of std::numeric_limits::digits number of digits in base-radix can represented type t without change. integer types, number of bits not counting sign bit. and later states char result char_bit - std::numeric_limits<char>::is_signed . and c numeric limits reference : char_bit number of bits in byte so normal modern computer, char 8 bits, char_bits equal 8 , digits function return either 7 or 8 depending on if char sign...

in answer question mentioned code posted wouldn't work if variable declared const . what if want initialize long array that's const type int main (){ const int ar[100]; //this invalid in c++ //something (int i=0;i <100;++i) ar[i]=i; return 0; } are there other ways using #define method proposed in question? there's no way directly, without hacks. in c++ 1 way work around problem take advantage of fact inside constructors const objects still modifiable. so, can wrap array class , initialize in constructor struct arr { int a[100]; a() { (unsigned = 0; < 100; ++i) a[i] = i; } }; and declare const arr arr; of course, have access arr.a[i] , unless override operators in arr .
