c++ iteration exception over int array

Question

why does the code cause exception ?

exception: Access violation writing location 0x000001A88BF5D000.

int* ints = new int(1000000);
for (int i = 0; i < 1000000; i++)
{
    ints[i] = 1;

Answer 1

You're allocating a single integer. If you want to allocate an integer array, you should use square brackets.

int* ints = new int[1000000]();
