pointers

[ework0 <ework0@gmail.com>]

Hello,

I would like to know what are the advantages of use pointers to 
insert/modify values in an array of characters for example.

char myword[2];
*myword = 'h';
*(myword + 1)='i';

why would i use this ( the intruction: *(myword + offset))?
what is the advantages of use this manipulation of array with these 
pointers ?
In the last line, do I increment the address that contains what s points 
to right ??
Why I increment it in '1' instead of a memory word concept?

Thanks
