How can you positioning the file using fseek ()?
Basic Syntax of fseek() in C/C++
- SEEK_SET -> We place the initial position at the start of the file, and shift from there.
- SEEK_CUR -> The initial position is taken at the current position of the existing file pointer.
- SEEK_END -> We place the initial position at the end of the file.
What role does the Fseek play and how many arguments does it have?
As explained above in the syntax of fseek() function, it takes 3 arguments, the first one being the file pointer, the second one being the number of bytes/ characters to be moved and the third defines the position where the file pointer to be moved.

Answer: The fseek() function is used to set the file pointer to the specified offset.
What is offset in Fseek in C?
fseek() in C/C++ fseek() in C language, is use to move file pointer to a specific position. Offset and stream are the destination of pointer, is given in the function parameters. If successful, it returns zero. If it is not successful, it returns non-zero value. offset − This is the number of bytes from the position.
What does Ftell return?
In C language, ftell() returns the current file position of the specified stream with respect to the starting of the file. This function is used to get the total size of file after moving the file pointer at the end of the file.
How do you use Fseek in C++?
The fseek() function in C++ sets the file position indicator for the given file stream. The fseek() function is defined in header file….fseek() Parameters.
| Value | Description |
|---|---|
| SEEK_SET | Beginning of file |
| SEEK_CUR | Current position of file pointer |
| SEEK_END | End of file |

The C library function int fseek(FILE *stream, long int offset, int whence) sets the file position of the stream to the given offset.
How do you use F seek in C++?
fseek() in C/C++ with example. fseek() is used to move file pointer associated with a given file to a specific position. Syntax: int fseek(FILE *pointer, long int offset, int position) pointer: pointer to a FILE object that identifies the stream. offset: number of bytes to offset from position position: position from where offset is added.
What is the difference between fseek_set and F seek_Cur?
SEEK_CUR: It indicates the current position of the pointer of the file. SEEK_END: As the name indicates, it moves the pointer of the file to the end of the file. SEEK_SET: As the name indicates, it moves the file pointer to the beginning of the start of the file How does fseek () function work in C?
What is the fseek() function of library header stdio?
