Virtual function

I have a virtual function:

virtual void set_num(double number = 56.00);

I also have a function get_num().

In the virtual function, if a value is greater than 100, I have to set it to 100.

Code:

---

set_num(double number)
{
       
        if (number > 100.0)
        {
                number1 = 100.0; // number1 is a private instance method
        }
       
}

---

If I dont specify a value, I dont get the default 56.00 printed, and if I put a number over 100, it doesnt output 100.

Thanks

I fixed one problem, but another one came up.

I have a default value of 56.00, and when I call that function with no parameter, it doesnt set the instance varialbe number1 to 56.00. How can I accomplish that?

Thanks

Is this in the base class or a derived class? Can you show us something compilable that demonstrates the problem?

-Prelude

This is in the base class.

I have a function

virtual void set_num(double number = 56.00);

I have an instance variable number1;

A funvtion get_num(), returns the instacne variable number1.

So, if I use set_num(), with no argument, wanting the 56 defaulted, it wont set numbe1 to 56.00.

Do you have another set_num() declaration (one with no parameters). Although your compile would warn you of something like that I can't think of any other reason why you are having trouble. Also, make sure you are putting the default in the actual declaration of the class i.e.

Code:

---

class myclass {
    void set_num(double=56.0);
};

---

If you only put it where you are defining the function then the compiler won't know what to do with the default value.
