Hi guys,

Say, I have the below function header (with default parameter) in c++

Code:

void myfunc(int a, int b=10, int c=5, int d);

How shall I call myfunc, if......

Quote:

1. If i do not wan to specify param b and c
2. If i do not wan to specify param c

Please help. Cheers,
Chinho

Hint - any argument that has a default needs to be *last*.

For example:

Default arguments are used only in function calls where trailing arguments are omitted — they must be the last argument(s). Therefore, the following code is illegal:

Code:

int print( double dvalue = 0.0, int prec );
