Question 1
What happens when you attempt to compile and run the following code?
#include <iostream>
using namespace std;
#define DEF_A 0
#define DEF_B DEF_A+1
#define DEF_C DEF_B+1
int main(int argc, char *argv[]) {
cout << DEF_C;
return 0;
}
Question 2
What happens when you attempt to compile and run the following code?
#include <iostream>
using namespace std;
int x=5;
static int y;
int i=0;
void static myFunction()
{
y=x++ + ++i;
}
int main (int argc, const char * argv[])
{
x++;
myFunction();
cout<<y<<" "<<x<< " " << i;
}
Question 3
What happens when you attempt to compile and run the following code?
#include <iostream>
using namespace std;
class A {
public:
void Print(){ cout<<"A";}
};
class B:public A {
public:
virtual void Print(){ cout<< "B";}
};
class C:public B {
public:
void Print(){ cout<< "C";}
};
int main()
{
A ob1;
B ob2;
C ob3;
B *obj;
obj = &ob2;
obj?>Print();
obj = &ob3;
obj?>Print();
}
Question 4
Which code, inserted at line 18, generates the output "AB"
#include <iostream>
using namespace std;
class A
{
public:
void Print(){ cout<< "A";}
void Print2(){ cout<< "a";}
};
class B:public A
{
public:
void Print(){ cout<< "B";}
void Print2(){ cout<< "b";}
};
int main()
{
B ob2;
//insert code here
ob2.Print();
}
Question 5
What is the output of the program if characters 't', 'e', 's' and 't' enter are supplied as input?
#include <iostream>
#include <string>
using namespace std;
int main()
{
string s;
getline( cin, s );
cout << s << " " << s.length();
return( 0 );
}
