I am getting this warning but all functions working properly .
what does this really means?
\'strcpy\': This function or variable may be unsafe.
Con
Since VC++ 8 strcpy() and a huge set of other functions are considered to be unsafe since they don't have bounds checking and can lead to a buffer overrun if misused.
You have two options:
_CRT_SECURE_NO_WARNINGS prior to including CRT headers and this will make the warning go away.
