Accepted Answer

A) compile-time error 
B) preprocessing error 
C) runtime error 
D) runtime exception

Question 2

Accepted Answer

A) compile time error 
B) garbage 
C) 0 
D) 5

Question 3

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

Accepted Answer

C) constructor called

Exam 4: C++ Programming and Concepts: Inheritance, Data Types, Objects, and Output Prediction

What happens when a class with parameterized constructors and having no default constructor is used in a program and we create an object that needs a zero-argument constructor?

Predict the output?#include <iostream> using namespace std;class Test{int x;Test() { x = 5;}};int main() {Test *t = new Test; cout <<t->x;}

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