c++ - How works deprecated warnings and how to remove them when using JsonCpp? -


i compiled vs 2015 jsoncpp , able link , everythign works fine.

however, i'm getting tones of deprecated warnings. classes marked depecrated in code:

class jsoncpp_deprecated("use streamwriter instead") json_api writer {...};

with 

#define jsoncpp_deprecated(message) __declspec(deprecated(message))

thing don't use classes. i'm getting messages file included. compiling this:

#include <json/json.h>  int main( int argc, char* argv[] ) {      return 0; }

produces 13 deprecated warnings...

isn't warnings supposed reported when deprecated class/function used? there way have work way? (i disable warning c4996, better keep enabled, reported when deprecated class/function used).

i think problem is, classes derive writer. counts being used. have no idea how rid of warnings, though.

edit: tested it. produces same warning 5 times, without being used.

test.h

class __declspec(deprecated("depricated warning unusedclass")) unusedclass { public:     void seti(int &val); };  class __declspec(deprecated("depricated warning unusedclass")) unusedclass2 : unusedclass { public:     int geti();     int i; };

test.cpp

void unusedclass::seti(int &val) {     val = 0; }  int unusedclass2::geti() {     return 10; }

warning:

warning 7   warning c4996: 'unusedclass': depricated warning unusedclass    c:\users\admin\documents\test.h 144

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
