Definition of const object

Show all headers | View raw

The standard mentions that modifying a const object results in
undefined behavior, but I couldn't find a definition of const object.
Can a heap-allocated object be a const object?

#include<iostream>

int main() {
   const int* p = new const int(42);
   // Modifying a const objects is undefined behavior.
   // Does p point to a const object?
   *const_cast<int*>(p) = 24;
   // Is it required to print 24?
   std::cout<<  *p<<  std::endl;
}
