What happens when you attempt to compile and run the following code?

#include <iostream>

using namespace std;

int main()
{
int x=0;
int *ptr;

ptr = &x;
cout<<x<<" "<<*ptr;

return 0;
}

Given:

#include <iostream>
#include <exception>
using namespace std;

int main () {
try
{
int * myarray= new int[1000];
}
catch (bad_alloc&)
{
cout << "Error allocating memory";
}
catch (exception& e)

{
cout << "Standard exception";
}
catch (...)
{
cout << "Unknown exception";
}
return 0;
}

What will happen if we use the operator "new" and the memory cannot be allocated?

What happens when you attempt to compile and run the following code?

#include <iostream>

using namespace std;

struct {
int x;
char c;
union {
float f;
int i;
};
} s;

int main (int argc, const char * argv[])
{

What is the output of the program?

#include <iostream>
#include <string>

using namespace std;

int main () {
string s1 = "Hello", s2 = "World";
s2 = s1 + s2;
cout << s2;
return 0;
}
