用户定义数组大小

Question

我发现创建一个用户定义大小的数组很困难。它显示错误，任何人都可以教我如何做到这一点吗？

int main()
{
    int row, column;
    cout << "Enter the amount of row" << endl;
    cin >> row;
    cout << "Enter the amount of column" << endl;
    cin >> column;
    int array[row][column]; //the value of variable cannot be used as a constant
    system("pause");
}
