EOF end of file

There is no special character as EOF at the end of ascii files
Both Windows and Linux have file systems that always know the exact length in bytes of the contents of a file, and have absolutely no need of any special character marking the file’s end.

Long back system used to read in BLOCK fashion and then they needed special character Control-Z character decimal code 26, hex 1A

 In C and C++  in file stdio.h we do have

#define EOF (-1) 

It is used as the return value of functions like int getchar(void)
