Fromw what I rememebr A[i] in C is just a shorthand for indirecting from a
pointer, and i[A] should be exactly the same thing. Hence the program
thakss one character at a time from the character array containing
"Hello, world\n" and output it.

Yes, C DOES permit an empty condition clause.
Valid, and often used when
a programmer prefers to use the "for" rather than "while" keyword.
C permits a lot of interesting things. I've occasionally interviewed
programmers claiming to be C experts, and amongst my questions for them
are whether the following is valid C code, what will happen when it is
executed, and why:
#include <stdio.h>
int main ()
{
int i;
for (i = 0; i < 14; i++)
putchar (i ["Hello, world!\n"]);
}
