It is. Don't you wish you had said that to begin with?

Solution 1

Yeah, it's 5. But the question YOU have to answer is why. This is your homework assignment, not ours.

The point of the exercise is to see if YOU understand what's going on, not if we do.

Yeh i think i understand it. the Pointer is pointing to the 3 and then adds two? therefore 5?

Dave Kreskowiak 11-Dec-15 21:56pm

You're thinking in terms of the contents of the array, not the array itself.

Member 12197225 11-Dec-15 22:00pm

I'm not sure what you mean, sorry?
Is it pointing at the 3rd element (the 5)??

Member 12197225 11-Dec-15 22:03pm

Got it thanks. But why is the pointer picking a value + 'Random Number'

Like Solution 2 says, you need to read up on pointers and arrays.

Solution 2

Sounds like you need to read up on arrays and pointers. Have a look at this[^] and see if you can understand it then.

Come to think about, this is the best advice, a 5.
