eroare la build

[seaza]

am urmatoarea eroare la build solution:

error LNK2019: unresolved external symbol "public: class multime __thiscall multime::operator+(class multime &)" (??Hmultime@@QAE?AV0@AAV0@@Z) referenced in function _main

codul este:

any ideas?

[nedo]

Pentru ambele definitii ale operatorului + ai uitat sa pui inainte multime

tu ai definit doar

multime operator+(argumente)

trebuia

multime multime::operator+(argumente)

[seaza]

dap...

multime multime:: operator+(multime& m)

{

multime m1;

int i;

for(i=1; i<100; i++)

m1.mult=mult | m.mult;

return m1;

}
