Can a heap-allocated object be const in C++?

Question

In C++ a stack-allocated object can be declared const:

const Class object;

after that trying to call a non-const method on suc

Answer 1

Yes, a heap-allocated object can be const. Consider this excerpt from the example in 7.1.5.1/5:

const int* ciq = new const int (3);    // initialized as required
int* iq = const_cast(ciq);       // cast required
*iq = 4;                               // undefined: modifies a const object

The example you gave in the question is fine because you're not asking new to make a const object; you're just storing the result in a pointer-to-const.
