Question 1

Output of following program?#include<iostream> using namespace std; class Point {Point() { cout <<"Constructor called"; }};int main(){Point t1; return 0;}
A)compile time error
B)run time error
C)constructor called

Accepted Answer

The constructor of the class `Point` is private, which means it cannot be accessed directly outside the class. Attempting to instantiate an object `t1` of class `Point` in the `main` function will lead to a compile-time error because the constructor cannot be accessed.

Question 2

#include<iostream> using namespace std; class Point {public:Point() { cout <<"Constructor called"; }};int main(){Point t1, *t2; return 0;}
A)compiler error
B)constructor called constructor called
C)constructor called

Accepted Answer

The answer of #include<iostream> using namespace std; class Point {public:Point()...

Question 3

#include<iostream> using namespace std;class X{public:int x;};int main(){X a = {10};X b = a;cout <<a.x <<" " <<b.x; return 0;}
A)compiler error
B)10 followed by garbage value
C)10 10
D)10 0

Accepted Answer

The answer of #include<iostream> using namespace std;class X{public:int x;};int main(){X...

Output of following program?#include<iostream> using namespace std; class Point {Point() { cout <<"Constructor called"; }};int main() {Point t1; return 0;}

#include<iostream> using namespace std; class Point {public:Point() { cout <<"Constructor called"; }};int main() {Point t1, *t2; return 0;}

#include<iostream> using namespace std;class X{public:int x;};int main() {X a = {10};X b = a;cout <<a.x <<" " <<b.x; return 0;}
