Question 1

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

#include <iostream>
using namespace std;
int main()
{
cout<<127<<", ";
cout.setf(ios::hex);//LINE I
cout<<127<<", ";
cout.setf (ios::showbase ); //LINE II
cout<<127<<", ";
return 0;
}




program outputs: 127, 7f, 0x7f



program outputs: 127, 7f, 7f



compilation error in LINE I



runtime error at LINE II



program outputs: 127, 0x7f, 0x7f

,compilation error in LINE II



program outputs: 127, 127, 127, (but it is an unpredictable result)
