Answer

In structured programming languages such as C, the declaration of objects is different compared to object-oriented programming languages such as Visual Basic and C#. In structured programming languages, objects are typically declared using data types that are built-in or user-defined in the language. These data types may include primitive types such as integers, floating-point numbers, and characters, as well as user-defined types such as structures and unions.

When declaring objects in structured programming languages, the programmer specifies the data type of the object, followed by a variable name. For example, in C, an integer object can be declared as follows:

“`
int myInteger;
“`

This declares an object named “myInteger” of type “int”, which is a built-in data type representing integers.

Apart from declaring individual objects, structured programming languages also allow the creation of arrays to store collections of objects of the same type. For example, an array of integer objects can be declared as follows:

“`
int myArray[5];
“`

This declares an array named “myArray” that can hold 5 integer objects. Each element of the array can be accessed using an index, such as “myArray[0]”, “myArray[1]”, and so on.

In contrast, object-oriented programming languages such as Visual Basic and C# provide a more specialized syntax for object declaration. In these languages, objects are declared using classes or structures that define the blueprint for the objects. Classes and structures include both data members and member functions, which collectively represent the behavior and state of the objects.

To declare an object in an object-oriented programming language, the programmer specifies the class or structure name followed by the object name. For example, in Visual Basic, an object of class “Car” can be declared as follows:

“`
Dim myCar As Car
“`

This declares an object named “myCar” of type “Car”, which is a class that represents cars. Similarly, in C#, the same declaration would look like this:

“`
Car myCar;
“`

In object-oriented programming languages, objects can also be created using the “new” keyword, which invokes the class or structure constructor to initialize the object. For example, in Visual Basic, a new instance of the “Car” class can be created as follows:

“`
myCar = New Car()
“`

This creates a new object of type “Car” and assigns it to the “myCar” variable. The constructor of the “Car” class is called to initialize the object.

Overall, the main difference between object declaration in structured programming languages and object-oriented programming languages lies in the syntax and the use of classes or structures in the latter. Object-oriented programming languages provide a more sophisticated way of declaring and creating objects, allowing for more flexibility and modularity in program design.
