c++ - How to make use of structure in another class? -

okay hello guys, have problem current assignment

i have 2 classes, namely employee class, , gm class.

in employee class, there structure used, namely

struct einfo {     char username [80];     char password [80];     int eid; };     

however, in gm class, have functions rely on struct in employee class. example,

void addemployee(fstream&, int, einfo&); void delemployee(fstream&, int, einfo&); void editemployee(fstream&, int, einfo&); 

how suppose make use of that?

what have tried redeclaring

struct einfo {     char username [80];     char password [80];     int eid; }; 

inside gm class. not work well. no syntax error, when im using

fstream afile; afile.open("employeeinfo.dat", ios::in | ios::out | ios::binary);

the file turns out empty itself.

any idea how fix ??

if struct einfo declared inside employe should refer employe::einfo when outside employe. if redeclare inside gm compiler consider employe::einfo , gm::einfo 2 different classes.
