can u tell why cant we go backwards in c++ even if we use seekp() and tellp() but where has we can go backwards in turbo c++

Of course you can iterate an array forth and backwards.

http://www.cplusplus.com/reference/ostream/ostream/seekp/ What are you trying to imply by 'go backwards'?

'Go backwards' in the sense of? Program execution? Program output?

well thats not right. not at all. can go either way or at random..

backwards from where?

from example an array yashas u cannot go from s-y but we can go from y--s

means u can't go backwards in c++ correct/wrong
