feof() - I/O Function
How is feof() used in C++?
How to check file position indicator for EOF?
Explanation
feof() is an I/O function that checks the file position indicator for the EOF of the associated stream. This check end of file indicator is generally set by a previous operation on the stream that reached the End-of-File. This function returns a non zero value if the EOF is reached, otherwise "0" is returned.
int feof ( FILE * stream );
Result :
Total bytes read in the file: 11
In the above example the "feof()" is used to find the total number of bytes read in a text file. The content of the text file is "ABCA1@@ABNM".
Syntax:
int feof ( FILE * stream );
Example :
| #include <stdio.h> int main() { long count = 0; FILE * stri = fopen ("getceg.txt", "r"); if( ferror(stri) ) { perror( "Error in File" ); } while (!feof (stri)) { fgetc (stri); count++; } fclose (stri); printf ("Total bytes read in the file: %d\n", count-1); return 0; } |
Result :
Total bytes read in the file: 11
In the above example the "feof()" is used to find the total number of bytes read in a text file. The content of the text file is "ABCA1@@ABNM".
