Again, using the standard method of capitol letters being wt and lower case being mutant, it makes figuring out CCGg a lot easier.
In this case C/c are for the caramel gene and G/g are for ghost.
So CC = means its wt and not het for caramel as there is no "c". Gg means its het for hypo since there is one G and one g. Because these are both recessive traits, you need to copies for the phenotype to be present.
Thus CCGg would be just a het ghost.
For a caramel glow, the genotype would be ccgg and a 100% wt snake would be CCGG.
Best way is to just take some different combinations and work them out on your own. And try using the capitol letter for wt and lower case for mutant with same letter for each allele on a gene to try and get used to this method.
Trust me when I say in the long run it will be a lot easier than using "n"
