If there is one, point out an error in the program
#include <iostream>
using namespace std;
int main()
{
int c = 'a';
switch(i)
{
case '2':
cout<<"OK";
case '1':
cout<<"Error";
default:
break;
}
return 0;
}

What is the output of the program?
#include <iostream>
using namespace std;
#define SQR(x)(x*x)
int main(int argc, char *argv[]) {
int x, y=2;
x = SQR(y);
cout << x << ", " <<y;
return 0;
}

What happens when you attempt to compile and run the following code?
#include <iostream>
using namespace std;
#define DEF_A 0
int main(int argc, char *argv[]) {
cout << DEF_A;
return 0;
}

Which code, inserted at line 19, generates the output "23"?
#include <iostream>
#include <string>
using namespace std;
class A {
int x;
protected:
int y;
public:
int z;
A() { x=1; y=2; z=3; }
};
class B : public A {
string z;
public:
int y;
void set() { y = 4; z = "John"; }
void Print() {
//insert code here
}
};
int main () {
B b;
b.set();
b.Print();
return 0;
}

Which code, inserted at line 8, generates the output "100"?
#include <iostream>
using namespace std;
int fun(int);
int main()
{
int *x = new int;
*x=10;
//insert code here
return 0;
}
int fun(int i)
{
return i*i;
}
