const member error

[Schlangenmensch]

@tampere2021 sagte in const member error:

inline ABC const fn_3();

This is simply not a const function The const has to be on the right side of the function signature.

Inline is another topic and has no effect on the constness.

@Schlangenmensch I guess this is the right const member function. If I modify the code by removing const, then it compiles fine.
static void fn_2(const int* const) const; //original code
static void fn_2(const int* const); //modified code

@tampere2021 I guess below line is the final const that makes it a const member.
ABC fn_1(const int*) const

@tampere2021 I guess, your guess is correct.

[tampere2021]

@Schlangenmensch do you mean to say this line guess is correct?
ABC fn_1(const int*) const

[Schlangenmensch]

@tampere2021

class ABC
{
public:
  ABC fn_1(const int*) const;
};

This is a class with a const member function which returns an object of the class itself.

This is a class with a const member function which returns an object of the class itself.

... without modifying members of the instance.

@VLSI_Akiko Thanks a lot, I am clear now.
