Hej
Jeg har et program men kan ikke faa det til at virke...
Det programmet skal goerer er at spoerge om et Id nummer som den saa henter informationer fra filen "it2171.txt" fra.
Filerne er main.cpp, it2171.cpp og it2171.txt
Fejlen som programmet melder er foelgende:
main.cpp(38): warning C4018: '<' : signed/unsigned mismatch
main.cpp(39): error C2065: 'id' : undeclared identifier
Nogen som kan hjaelpe ?????
