My path to C/C ++-011 lessons (Reading files)

Previous: http://www.bkjia.com/kf/201205/130088.html

Now let's talk about file operations and reading files in byte. It's actually very simple. I believe everyone will talk about them separately. Otherwise, everyone will not be in the mood to read long code.

 

[Cpp]
# Include <stdlib. h>
# Include <stdio. h>
 
Void readFile ()
{
FILE * file; // FILE pointer
Char c; // read characters
File = fopen ("c: \ test.txt", "r"); // open the file
If (NULL = file) // determines whether the file is successfully opened.
{
Printf ("can't open this file, make sure the file exist !!! \ N ");
Exit (1 );
}
Puts ("open file successful !!! ");
Puts ("read file now :");
 
C = fgetc (file );
While (c! = EOF) // The End of the file is EOF
{
Putchar (c );
C = fgetc (file );
}
Printf ("\ n ");
Fclose (file); // remember to close the file
}
