Re: [Objc-discuss] Why Sementation fault?

[David S. <st...@te...>]

Hi,

int i is of type 'int' , not 'id' (not an Objective-C Object).

Basically the idea of the Computer Algebra Kit is to provide Objective-C
objects for computer algebra and integer arithmetic, so you could do:

   [aCltn add:[BigInt int:i]];

or something like

   [aCltn add:[BigInt factorial:i]];

If I run the program,

#include <stdio.h>
#include <objpak.h>
#include <cakit.h>

int main(void) {
	id aCltn = [OrdCltn new];
	int i = 0;
	for(i = 1; i < 100; i++) {
		[aCltn add:[BigInt int:i]];
	}
	for(i=0;i<[aCltn size];i++) [[aCltn at:i] printLine];
	return 0;
}


$ objc -o bigint bigint.m

it works

Regards,
David Stes
