const member functions can call const member functions only?
- by Abhi
Hi all.
Do const member functions call only const member functions?
class Transmitter{
const static string msg;
mutable int size;
public:
void xmit() const{
size = compute();
cout<<msg;
}
private:
int compute() const{return 5;}
};
string const Transmitter::msg = "beep";
int main(){
Transmitter t;
t.xmit();
return EXIT_SUCCESS;
}
If i dont make compute() a const, then the compiler complains.
Is it because since a const member function is not allowed to modify members, it wont allow
any calls to non-consts since it would mean that the const member function would be 'indirectly' modifying the data members?
