What does FEOF mean in C?

Test for End-of-File
(Test for End-of-File) In the C Programming Language, the feof function tests to see if the end-of-file indicator has been set for a stream pointed to by stream.

What is FEOF used for?

The feof() function indicates whether the end-of-file flag is set for the given stream . The end-of-file flag is set by several functions to indicate the end of the file. The end-of-file flag is cleared by calling the rewind() , fsetpos() , fseek() , or clearerr() functions for this stream.

What is the difference between EOF and FEOF?

Main difference EOF is a value to compare upon characters to check whether end of a stream has reached and feof is a function call to check a file pointer has reached end of that file. EOF is a condition in a computer operating system where no more data can be read from a data sources.

Can u rely on FEOF () function?

1 Answer. You should not use feof() to loop on – instead, use the return value of fread() – loop until it returns zero.

What does FEOF () return if end of file was reached?

The function feof() is used to check the end of file after EOF. It tests the end of file indicator. It returns non-zero value if successful otherwise, zero.

What is fgets function in C?

The fgets() function in C reads up to n characters from the stream (file stream or standard input stream) to a string str . The fgets() function keeps on reading characters until: a newline character is encountered. end of file (EOF) is reached.

How does GETC work in C?

The C library function int getc(FILE *stream) gets the next character (an unsigned char) from the specified stream and advances the position indicator for the stream.

What library is FEOF in?

C library function – feof() The C library function int feof(FILE *stream) tests the end-of-file indicator for the given stream.

Does FEOF move the file pointer?

feof () function finds end of file. SEEK_END moves file pointer position to the end of file. ftell () ftell () function gives current position of file pointer.

How do you reset a FEOF?

The function feof() tests the end-of-file indicator for the stream pointed to by stream, returning nonzero if it is set. The end-of-file indicator can only be cleared by the function clearerr().

What is FEOF Stdin?

Expression feof(stdin) is true if an attempt to read the standard input has been done, and the standard input was found to have nothing left in it. Be cautious with eof. It does not ask whether there is anything left in the standard input. It only returns true if you have already tried to read past the end of the file.

What is the difference between GETC() and feof() in C++?
