Pointers, please check?

Can someone check if I got these correct please?? I'm pretty sure I missed almost half of these so I really need help on these. If someone can explain too, that would be really nice.

a: 5
b: address of location of x (0x....)
c: address of value x (0x...)
d: address of value x (0x...)
e: 5
f: 3
g: 3
h: 6
i: 9
j: vals
k: address of vals + 1
l: address of ptrVals + 2
m: 0
n: 55
o: 55
p: 0
