c++ - Conflict between boost:type_erasure and boost::iterator_facade -


consider simple program:

#include <boost/type_erasure/is_placeholder.hpp> #include <boost/iterator/iterator_adaptor.hpp>  int main() {     return 0; }

this fails compile with: 

  include/boost/type_erasure/is_placeholder.hpp:31:33: error: reference 'use_default' ambiguous     struct is_placeholder< ::boost::use_default> : ::boost::mpl::false_ {};                                     ^     include/boost/iterator/iterator_adaptor.hpp:44:18: note: candidate found name lookup 'boost::use_default'     using iterators::use_default;                      ^     include/boost/type_erasure/is_placeholder.hpp:21:8: note: candidate found name lookup 'boost::use_default'     struct use_default;            ^     1 error generated.

i don't want go , change header files. how around issue?

a temporary solution replace 

struct use_default;

in `boost/type_erasure/is_placeholder.hpp' with

namespace iterators {     struct use_default; } using iterators::use_default;

which found in `boost/iterator/iterator_adaptor.hpp'.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
