Thread: does C have a delete function??

remove() is stdio.h
unlink() is in unistd.h <-- Unix only

[edit] I presumed you were talking about deleting files?[/edit]

That looks like c++ to me....

The same with me. In school, we were taught C and C++ at the same time. The only difference I know is some obvious things like printf/cout, scanf/cin, malloc/new, free/delete and structure/class...

you got taught C++ at school?? Lucky bastard... I don't even think the computer teacher(s) at my school even know HTML! My computer teacher is some old guy who talks about the old computers that took up 20 rooms every lesson and if you havn't done your homework and you don't want him to come around and check it, you just ask him a question that he doesn't know the answer to like "Whats the difference between a Mac and a PC" and he babbles on about nothing for the rest of the lesson I learn/have learned everything I know from books (and a bit from this board )

Anyway, congratulations to your own custom title (400+ posts)

>If yes..in which library can it be found?
If you mean the delete operator in C++ which frees allocated memory then the corresponding C function is free(), found in stdlib.h.

Code:

// Allocate on the heap 
char* Array = new char[99]; 

//Reclaimed with delete 
delete [] Array;

Converted to C this would be

Code:

/* Allocate memory */
char *Array = malloc ( 99 * sizeof *Array );

/* Reclaimed with free */
free ( Array );

From the good book (K&R that is)

The sizeof operator yields the number of bytes required to store an object of the type of its operand......

Yeah. You wouldn't want to use Java. I mean really, then you don't get to use the arrow operator at all!

I like Java. For the most part, Java is like C or C++. They have a very similar syntax. If you know one, it's not too hard to be able to read the code of another. Generally speaking anyway.

Quzah.
