Mixing default and non-default parameters in Constructor?

[desktop]

Are there some way to mix default and non-default parameters in a
constructor:

class test {

public:
test(int i = 45, int j) : pp(j){}
private:
int pp;
int i;
};

The above does not work and gives the error:

main.cpp:144: error: default argument missing for parameter 2 of
‘test::test(int, int)’
make: *** [main.o] Error 1

Yes, but default arguments have to be the last one[s].

Default parameters must be at the *end* of the parameter list.
Note also, that you did not initialize your member variable "i".
