0;
i++;
goto lab;
i++;
lab:
cout<<i;
return 0;
}
- It prints: 0
- It prints: 34
- It prints: 1
- It prints: 3
Correct answer: C
Question 2
What is the output of the program?

{
char str[] = 'Hello\0\World\0';
cout << str;
return 0;
}
- It prints: Hello
- It prints: World
- It prints: HW
- It prints: World\0World
Correct answer: A
Question 3
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;
}
- No Error
- Use of undeclared identifier 'i'
- Illegal use of 'continue'
- Illegal use of 'break'
Correct answer: B
Question 4
What happens when you attempt to compile and run the following code?

#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:
void set() { y = 4; z = 'John'; }
void Print() { cout << y << A::z; }
};
int main () {
B b;
b.set();
b.Print();
return 0;
}
- It prints: 4John

};
void setAge(Base &ob) {ob.age = 0;}
int main () {
Base a;
a.Print();
setAge(a);
