Question

What are some different types of data you would expect to manipulate, and how would you represent them in a program?

Answer 1

Every Program comprises of 2 main artifacts - Data and operations. Data can be represented using Data Types . They can be depicted as characters, arrays, numbers, booleans and structures. Structures , however, are replaced with objects in Object oriented world.

Below are high level types of data that a programmer could manipulate :

Characters ('a', 'b', ... 'z', '$', '#', etc)

Arrays (a list of data (of a particular Data Type!))

Numbers, (e.g., -5, -60.34,80.54).

Booleans (true or false)

Structures (a collection referring to a single entity)

Objects (instance of a class in Object Oriented language)

Representations

--------------------

a) Characters :

symbol = '#';

degree = '%';

b) Arrays

names =["Tom","Harry","John"]

c)Numbers

averageTemperature = 35;

major = 18;

  

d)Booleans

isButtonClicked = true;

e)Structures

We create a employee structure with various datatypes within it

employee.name = 'Harry';

employee.age = 28;

employee.salary = 4500;

employee.isManager = false;
