i have this info[35] can conntain 3

[vintl]

i have this info[35] can conntain 35 bytes, but now i only wan to extract the last 5 bytes and push it into DB, is this stmt correct?
start from byte ->30, and read only 5 byte.

memcpy(dorgnins_db.info, info[30], 5 );

memcpy() expects an address for the first and second arguments. Try this:

memcpy( dorgnins_db.info, info + 30, 5 );

On a another note, the info array contains 35 elements. This means the first element is number zero (info[0]), and the last element is 34 (info[34]). If you wanted to access the 30th element of the array using a subscript, you would reference it as info[29].
