How to change the variable in a speceific place in an array stored in the heap? (C++)

Question

Does anybody know how to change the value of an item of an array when the array is in the heap, y have tried with:

pointer = new int[2];
*pointer [0] = 0;
*pointer [1] = 1;
cout << *pointer[0] << " and " << *pointer [1] << endl;
delete []pointer;

according to code blocks there are errors in the 2, 3 and 4 lines.

obviously I have the main declaration, the include <iostream>, the using namespace std, the return 0 and everything.

please help!!!

Answer 1

p[0] is the same as *p
p[1] is the same as *(p+1)
*p[0] is the same as **p

So don't do that here :)

int* p = new int[2];
p[0] = 7;
p[1] = 4;
std::cout << p[0] << " " << p[1] << std::endl;

delete[] p;

Answer 2

Try changing it to:
*(pointer +1)
and
*pointer
where you wrote *pointer[1] and *pointer[0]
...Though it's not necessary, you have [] for this.

Thanks Jamie, but the code provided by Dennis worked (by the way, thanks Dennis)
