Function Header?

[Dkob1]

How is a function header coded when the function call should allow a mix of default and required arguments?

Give an example of a calls using zero, one, and two default arguments, with one required argument; and the header of the function called.

Would this be okay?

int mul(int ra, int rb=3, int rc=4);

Can you write the example, where mul is called with different number of arguments?

Didn't understand what you meant

Would this be okay?

int mul (int ra, int rb=3, int rc=4);

Yes, that is an acceptable function declaration for a function that takes 1 required argument and 2 optional arguments with default values. Required arguments must be specified before any default arguments.
