C version: (uses redirection/pipes)

#include <studio.h>

main()
{
	char c;

	while ((c = getchar()) != EOF) {
		if ((c >= 'A') && (c <= 'Z'))
			c = ((c-'A'+13) % 26) + 'A';
		else if ((c >= 'a') && (c <= 'z'))
			c = ((c-'a'+13) % 26) + 'a';
		putchar(c);
	}
}

sh version: (also uses redirection/pipes)
