Answer 1

You've already declared 'p'.
Also, just a size goes in the [] (no declarations).

int const p=5;
int ar[p];

Note: By convention, constants are written ALLCAPS and...I'm used to seeing 'const' first, like this:

const int P=5;

Answer 2

kirk's right, but just one more thing
to display an array item u must use ar[position num]
