The function fclose () in C

Int fclose function (FILE * stream) in Library C closes Stream. All buffers are flushed (erased or moved to the periphery).

Declare the function fclose () in C

Here is the declaration for fclose () function in C:

 int  fclose ( FILE  * stream ) 

Parameters

This method returns 0 if Stream is successfully closed. If failure, EOF is returned.

For example

The following program C illustrates the usage of the fclose () function in C:

 #include int  main () {  FILE  * fp ;  fp  =  fopen ( "baitapc.txt" , "w" );  fprintf ( fp , "%s" , "Hoc C co ban va nang cao tai QTM !!!" );  fclose ( fp ); return ( 0 ); }
