   Sets the file position indicator for the file stream stream to the value pointed to by offset. If the stream is open in binary mode, the new position is exactly offset bytes measured from the beginning of the file if origin is SEEK_SET, from the current file position if origin is SEEK_CUR, and from the end of the file if origin is SEEK_END. Binary streams are not required to support SEEK_END ...

   What is the output of fseek?

   • When we implement fseek (), we move the pointer by 0 distance with respect to the end of the file i.e. pointer now points to the end of the file. Therefore the output is 81. Suppose the file test.txt contains the following data: "Someone over there is calling you. we are going for work.

   What if fseek is a wide oriented stream?

   • If the stream is wide-oriented, the restrictions of both text and binary streams apply (result of ftell is allowed with SEEK_SET and zero offset is allowed from SEEK_SET and SEEK_CUR, but not SEEK_END). In addition to changing the file position indicator, fseek undoes the effects of ungetc and clears the end-of-file status, if applicable.
