Besides, * and [] are interchangeable. You can define a string as an array
and use it later as a pointer:
char s[] = "hola";
char x = s[1]; // Here x = 'o'
char y = *(s+2); // Here y = 'l'
And vice versa:
char *s = "hola";
char x = s[0]; // Here x = 'h'
char y = *(s+3); // Here y = 'a'
This is right, and the following sintax are analogous:
*(p+i) <---> p[i]
*(*(p+i)+j) <---> p[i][j]
This last one in the case of a double pointer.

This is because
*chars <---> *(chars+0) <---> chars[0]
are analogous. So, chars[0] changes from 1 to R.
