What is the output of the program?
#include
using namespace std;
#define PRINT(i) cout<
int main()
{
int y=2, z=3;
PRINT(y);
PRINT(z);
return 0;
}
What happens when you attempt to compile and run the following code?
#include
#include
using namespace std;
int main()
{
string s1[]= {"How" , "to" };
s1[0].swap(s1[1]);
for (int i=0; i<2; i++) {
cout << s1[i];
}
return( 0 );
}
What will happen when you attempt to compile and run the following code?

enum state s1, s2, s3;
s1 = ok;
s2 = warning;
s3 = error;
s4 = ok;
cout << s1<< s2<< s3;
return 0;
