the question is : if a const member function can call a non_const member
function
without const_cast,
if fun() changed the member in A,like this:
//const_test.cpp
struct A
{
A(unsigned int n)
{
aa=n;
}
void const_fun() const
{
static_cast<A>(*this).fun(); //ok
// fun(); //err
}
void fun()
{
aa=78;
}
unsigned int aa;
};
int main()
{
const A a(56);
a.const_fun();
}
the sematic of bitwise constness is not confirmed.
this program is inspired from the book <Effective C++>(third edition)
Item3: use const whenever possible
