[solved] error: default argument missing ?

[deleted28]

Hello,
do i always need to assign all functionparametrs a default value when giving at least a single one except it's the last parameter ?

in header

void logIt(quint8 _level=0b11111111, QString _dir="**", QByteArray _ba=NULL);

void logIt(quint8 _level, QString _dir, QByteArray _ba);

void logIt(quint8 _level, QString _dir, QByteArray _ba=NULL);

all the above are OK, but not :

void lvoid logIt(quint8 _level=0b11111111, QString _dir, QByteArray _ba=NULL);

void logIt(quint8 _level=0b11111111, QString _dir="**", QByteArray _ba);

error: default argument missing for parameter 3 of 'void

[darkp03]

The default parameters must always be the last ones., for example

void Function( unsigned char a, unsigned char b, unsigned char c=0x20);

Will work nicely, but

void Function( unsigned char a, unsigned char b =0x20, unsigned char c);

Wont compile, on your case, you can fix it easily just by changing the order in the parameters

void logIt(QByteArray _ba, quint8 _level=0b11111111, QString _dir="**")

Yes, sure, and it makes sense, thank you
