C++ pass by pointer, default declaration -

if in h file, there function:

void printdictionary(dict *dic, wordtype type=all){ }

and in corresponding cpp file, there function:

void printdictionary(dict *dic, wordtype type){ }

will there compilation error? or correct corresponding functions?

there's error since both have function body; you've defined same function twice, breaking 1 definition rule.

declare function in header

void printdictionary(dict *dic, wordtype type=all);                                                   ^ not {}

and define in source file did.

the default arguments should go on declaration in header, since needed call function using them. can't go on definition, definition correct is.
