Is it possible to print a variable's type in standard C++?

Question

For example:

int a = 12;
cout << typeof(a) << endl;

Expected output:

int

Answer 1

You may also use c++filt with option -t (type) to demangle the type name:

#include 
#include 
#include 

using namespace std;

int main() {
  auto x = 1;
  string my_type = typeid(x).name();
  system(("echo " + my_type + " | c++filt -t").c_str());
  return 0;
}
