Kod:
int main()
{
int a = 10;
const int * cp_val= &a;
auto& x = cp_val;
bool is_const_int_ptr = std::is_same<decltype(x), const int *>::value; // returns 0
// *x = 100; // error: assignment of read-only location '* x'
}
Kod:
#include <boost/type_index.hpp>
template<typename T>
void print_type(T)
{cout << "type T is: "<< boost::typeindex::type_id_with_cvr<T>().pretty_name()<< '\n';}
Kod:
print_type(x); // It returns int const*
