Can we create an array of objects for a class having default constructor Justify your answer?
See example code below. #include <iostream> class x { private: // Members. static int counter; int data; public: // Default constructor and destructor. x():data(++counter){printf("Object %d created!\n",data);} ~x(){printf("Object %d destroyed!\n",data);} // other members omitted for brevity... }; // Initialise static counter. int x::counter=0; int main() { // Instantiate an array of 10 objects. x arr[10]; // .. do some work with the array .. return( 0 ); // The array falls from scope, destroying the objects. } Example output: Object 1 created! Object 2 created! Object 3 created! Object 4 created! Object 5 created! Object 6 created! Object 7 created! Object 8 created! Object 9 created! Object 10 created! Object 10 destroyed! Object 9 destroyed! Object 8 destroyed! Object 7 destroyed! Object 6 destroyed! Object 5 destroyed! Object 4 destroyed! Object 3 destroyed! Object 2 destroyed! Object 1 destroyed!

What is OOP language?
Before Object oriented programming the term which was used was “Structural Programming” where a programmer has to use the predefined data types, they cannot define their own data type. But when the term object oriented programming start in programming programmer become able to define its own data type according to their own use. Here a coder can define its own data types called classes and then create object from these classes. Coding in Object Oriented language Advantages of Object Oriented Programming One of the main advantages of OOP over procedural programming techniques is that they enable programmers to create modules that do not need to be changed when a new type of object is added. A programmer simply can create a new object that inherits from existing objects many of its features . This makes object-oriented programs easier for programmer to modify.
