This is the first "blog" of any kind I've ever had, so it's probably not the greatest...

Just a little snippet about me:

I'd like to consider myself relatively tech-savvy; obviously I use Linux (Arch to be precise; K.I.S.S. FTW), and I enjoy learning new things about computers in general (both software and hardware-related).

This blog is mostly just for whenever I feel like telling the world about my experiences with computers/Linux (or just life in general), or just posting for the hell of it.

Code:

#include <stdio.h>
#include <string.h>
#include <malloc.h>

int main(int argc,char** argv)
{
    char* str = malloc(1);
	
    if(argc >= 2)
    {
        int i;
        for(i = 1; i < argc; i++)
        {
            strcat(str," ");
            strcat(str,argv[i]);
        }
        
        int len = strlen(str);
     
        while(1)
        {
            while(len--)
                putchar(str[len]);

            putchar('\n');
			
            len = strlen(str);
        }
    }
    else
    {
        while(1)
            printf("n\n");
    }

    return 0;
}

This is my silly little nod to the "yes" program. The only thing it does differently is that it prints the string reversed.

Code:

...flawlessly. It's even in my /usr/bin.

EDIT: Argh, I was right about one thing: it definitely terminates on SIGSEGV (segfaults when run without params).

EDIT of EDIT: The program has been revised...the first if clause was redundant, and the goto has been removed.

Output has also been edited (turns out it ain't perfect
