Hello guys ..
Im writing an small project for my brother in c++ using files.. .
The Datas are stored correctly & retrieved for some time & later some symbols come into & replace the original data .

Using seekp() & im randomly writing some data , but that data is not correctly written . .
Im writing objects to & from from File.. .
When i used reinterpret_cas t .. . its giving me undefined symbol error in my Turbo C .. .

Too much detail is missing from your question.

Like the disc file format.

I assujme all of your records are the same length and all have the same record layout and your new contents that are randomly written do not exceed the field width and that you are dropping the data in the correct spot.

Plus anytime I see reinterpret_cas t being used by a beginner, I smell trouble. Usually, in C++ if you have to cast you are a) calling a relic C function or b) your C++ design is weak.
