Write a second version of the median program $($

median$2.$cc$)$ which repeatedly asks the user to enter a positive number, and displays the median of the list of numbers entered so far. You should start with an array of size $0$ and increase the size of the array each time a new number is entered. Exit the program when the user entered an integer which is negative or $0.$ You should write the function:

int $*resize(int*A,$ int $n)$;

which increases the size of an array of $n$ elements to $n+1$ elements. The first $n$ elements should be copied to the new array. The pointer to the array is returned, and the original array passed into resize is deleted. An array of size $0$ should be represented by the nullptr pointer.
