Also, whenever an opened file needs to be reopened in other mode in such a case also the opened file
must be closed first. Closing the file enables to wash out all its contents from the RAM buffer and
further the link is disconnected from the file.
Example:
The function to close a file is
fclose(fp);
This statement closes the file associated with file pointer fp. This function closes one file at a time. In
order to close all files function syntax used is as follows:
fcloseall();
This function closes all the opened files and returns the number of files closed. It does not require any
argument.

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.
