Increasing Size Random Number Generator Triggering Breakpoint

I'm trying to create a random number generator which increasingly outputs +1 randomly generated number(s). My problem is, after the final loop, MVS throws an exception,

"RandomGame.exe has triggered a breakpoint. occurred."

I understand this has something to do with memory positions being corrupted, which makes sense as I'm utilizing a dynamically sized array but I'm not sure how to move forward.

int size = 1;

int* array = new int[size]; 

for (int x = 0; x < 5; x++)
{
        for (int i = 0; i < size; i++)
    {
        array[i] = (rand() % 100) + 1;
        cout << array[i] << endl;
    }

        size++;
}

return 0;

I expect the program to give me 15 randomly generated numbers and then return 0. While it outputs the numbers, after it finishes, it throws the exception.
