Static member default argument

[procastination]

I got this code:

class Screenet{
public:
	Screenet &clear(char = bkground);

private:
	static const char bkground;
};

One thing i dont understand is this
Screenet &clear(char = bkground);

static object can be use as default argument but i dont know about char=variable

So i declare bkground as char then I initiate a char via bkground? uhm im confused.

Can someone help me.

char is a reserved word. so im passing a bkground to a char? is that the case?

When you declare a function you can leave out the parameter name if you like.

void function(int paramName);

void function(int);

Specifying a default argument is no exception. You can still leave out the parameter name.

void function(int paramName = 123);

void function(int = 123);

SO how do you view that? int isnt a variable so does that mean function created a temporary variable as type int and pass 123?

[Peter87]

It means that the default argument for the first parameter is 123.
