c++ - How to test/verify that zero-initialization takes place -

-
i trying test 0 initialization on virtual machine g++ options -std=c++98, -std=c++03, -std=c++11 unfortunately there not many garbage values , see zeros in place shouldn't be. how force random values can test this? #include <iostream> #include <string> using namespace std; class { public: int a; }; class b { public: b(){} int x; }; int main() { { int tab[50000] = {0}; } a; a* aa = new a; b b; b* bb = new b; cout << a.a << endl; cout << aa->a << endl; cout << b.x << endl; cout << bb->x << endl; return 0; } you not guaranteed see random numbers. c/c++ standard says uninitialized values undefined, cannot values have. 0 ok (maybe virual machine zeros memory before allocating). if need random numbers, generate them using <random>

ruby - Why did I get `main.using is permitted only at toplevel` when I used a Refinement in IRB? -

-
i tried use refinement in irb (v0.9.6, ruby 2.3.0): module foo refine object def foo() "foo" end end end using foo # => runtimeerror: main.using permitted @ toplevel this the exact setup documentation (which results in same error). what went wrong? how fix this? it's either bug or misfeature of irb. well-known due pretty hackish way irb implemented, not behave correctly corner-cases. the incompatibility knows in ruby, methods defined @ top-level become private instance methods of object , whereas in irb, become public instance methods of object . obvious behavioral difference in irb, require_relative doesn't work, because searches relative current file, in irb, there is no current file. there differences in syntax gets accepted, believe, , local variables , when , aren't defined. so, not inconceivable there might behavioral differences wrt. refinements. in fact, myself have encountered error message, , running exact same c...
