Question

Function to access file in non sequential and random mode

Answer 1

The function that can best denote this condition is Write () and read () function.

The un-sequential and random mode of file works in a separate way from that of the sequential model.

In case of a sequential mode, one can read and write whatever or wherever anything is present.

However in case of an un-sequential mode, the random access  starts to function.

Here you can start to read and write from wherever you want.

However in case of a sequential  file, one can read them sequentially only.

Hence this is the limitation.

So sequential and non sequential and random modes are different from each other.
