Well did you run it to find out?

> printf("%s",p+p[3]-p[1]);
First you write it as

Code:

printf("%s",&p[ p[3]-p[1] ] );

Then you make the appropriate substitutions for p[3] and p[1] to get the actual values.

Then you look up 'X' and 'Y' (your actual two letters) in an ASCII table, to work out the maths.
