Full Discussion: Pointers and array
Top Forums Programming Pointers and array Post 302853329 by Corona688 on Friday 13th of September 2013 05:18:35 PM

This is a highly unusual way of using arrays and pointers.

Seeing where *pa starts may help:

Code:
printf("The first element of *pa is: %c\n", pa[0][0]);

The [1][0] has moved you one down the outermost dimension of the array, so it starts at {{'g', 'h'}, {'i', 'j'}, {'k', 'l'}}

[1][1] would move you one down and one in, so you'd start at {{'i', 'j'}, {'k', 'l'}}
