Pointers: I\'m studying for c++ exam and I want to see if what I have is right for this review questions. I think some of the ones I got on my paper are wrong, please write down what a...p come out too and that last part as well please....Thanks!
int x;

cout << \"n:\" << intRate << endl;
*ptrRate = 66;
cout << \"o:\" << intRate << endl;
int * const ptrY = &x;
ptrY = &vals[0];
cout << \"p:\" << *ptrY << endl;
const int * const ptrZ = &intRate;
ptrZ = &vals[0];
*ptrZ = 7;
Solution
a)5
b)b=address of location where x istored.
c)address of value x
d)address of value x stored in address of ptrX
e)5
f)3
g)3
h)6
i)9
.
