    return 0;
Error: unrecognised Keyword SEEK_SET
Error: fseek() long offset value
No error
None of above
Answer: Option

What is the meaning of

Vishal Babasaheb rahikar said:   6 years ago
Syntax for feel is;

fseek(file*stream,long offset value,int whence);
Here while providing offset value provide as 20L not 20 ,3rd argument have 3 macros SEEK_SET,SEEK_CUR,SEEK_END.

SEEK_SET means character seeking starts from the beginning of file, SEEK_CUR means starts seeking from last accessed word and SEEK_END means starts from end towards the beginning.

fseek(fp, "20", SEEK_SET);

The correct answer should be: Invalid conversion from const char* to long int.

seek_set = Cursor moves to first letter of the file .
seek_end = Cursor moves to last letter of the file.
seek_cur = Cursor starts when ever we accessed last world.
