What will be the output of the following C++ code?

#include <iostream>
using namespace std; 
int main()
{
    int x = -1;
    char *ptr;
    ptr = new char[256];
    try 
    {
        if (x < 0)
        {
            throw x;
        }
        if (ptr == NULL)
        {
            throw " ptr is NULL ";
        }
    }
    catch (...) 
    {
        cout << "Exception occurred: exiting "<< endl;
    }
    return 0;
}
