In OOP the automatic objects, constructors and destructors are called each time the objects

Enter and leave scope

Inherit parent class

Are constructed

Are destroyed

A program to find area of rectangle in Class Area in which use the Area (int a,int b) parameterized constructor to initialize length and breath, Area (2,4); initializing the data members in main Program

Output of following code ?include using namespace std; class construct { public: int a, b; // Default Constructor construct() { a = 10; b = 20; } }; int main() { // Default constructor called automatically // when the object is created construct c; cout << "a: " << c.a << endl << "b: " << c.b; return 1;

Comment each statment in program

#include

using namespace std;

class CopyCon {

int a, b;

public:

CopyCon(int x, int y) {

a = x; b = y;

cout << "\n the initialization of Constructor";

}

void Display() {

cout << "\nValues : \t" << a << "\t" << b; }

};

void main() {

CopyCon Object(30, 40);

//Copy Constructor

CopyCon Object2 = Object;

Object.Display();

Object2.Display(); }

Which among the following is not a necessary condition for constructors?

It must not have any return type

It must contain a definition body

It can contains arguments

How many types of constructors are available for use in general (with respect to parameters)?

Which among the following is correct for the class defined below?class student { int marks; public: student(){} student(int x) { marks=x; } }; main() { student s1(100); student s2(); student s3=100; return 0; }

Object s3, syntax error

Number of arguments and return type

Return type and type of arguments

Return type and definition

Which of the followings is/are automatically added to every class, if we do not write our own.

Copy Constructor.

Assignment Operator

A constructor without any parameter

All of above

State whether the following statements about the constructor are True or False. i) constructors should be declared in the private section. ii) constructors are invoked automatically when the objects are created.

True,True

True,False

False True

False,False

What is the output of this program? Note:Includes all required header files class find { public: find() { cout<< "find"; } ~find() { cout<< "course"; } }; int main() { find obj; return 0; }

A. The program will print the output find.

B. The program will print the output course.

C. The program will print the output findcourse.
