It deppends on function type what you implement:
class xxx
{
int x;
public:
void a() const;
//this function can't change class members,
//except mutable variables
}; John Fill

 

[Sedai]

exactly.

make it private and then make its accessor functions const
such as:

class MyClass{
public:
//...loads of hardcore code
int getVariable()const{return variable;}

private:
int variable; //your data variable
};

so now there's no way to change it unless of course you create a member function that can modify it such as

void MyClass::setVariable(int newValue){
   variable = newValue;
}
