my code includes this function
void read(set<string> &mySet);
but when i put this line in the header file, i get the following errors:
error: variable or field 'read' declared void
error: 'set' was not declared in this scope
error: 'string' was not declared in this scope
error: 'mySet' was not declared in this scope
so, what should i write to make this thing work?
thanks.
