Just consider pointers as arrays ;-)
As with a pointer like
char *tab;
char c;
you can do *tab=c; or the SAME tab[0]=c; so a pointer is an (unknown size) "array"
If your pointer ("array") come from a malloc() it give
you access to a block ("array") of memory
If it is the screen data pointer = it is an array of pixel
tab[320*3+64]=0; can set up as black the (x 64 y 3) pixel of a 256 colors screen ("array" of pixels)
If it is a string pointer so can change chars
tab[0]='H'; tab[1]='E'; tab[2]='L'; tab[3]='L'; tab[4]='O'; tab[5]=0; ("array" of chars)
