Thread: Pointer Assignment

Hey guys, I have a question as to whether or not I am assigning the following correctly.

The question states:
Assume the declaration

Code:

int m = 35, *intPtr;
double x, *dblPtr;

a) Assign intPtr a value so it points to m
b) Assign dblPtr a value so it points to x, amd then use the pointer to assign x the value of 5.3

On (a), I think it is:

Code:

intPtr = &m;

On (b), I think it is:

Code:

dblPtr = &x;
*dblPtr = 5.3;

I am questioning myself as to whether I should have used the * operator in assigning the first statements (for instance, *intPtr = &m and *dblPtr = 5.3)

I think I am right on the first set. Can someone please let me know? Thanks

Your code looks right as is.

Look at the two statements for dblPtr. One assigns an address, the other assigns a value. The pointer itself holds an address, which is why you assign directly to dblPtr. But the value should be assigned to the dereferenced pointer, which is why you added the * for the second one.
