Introductory modules - '5 basic Concepts of any programming language'

Question 1

Variables - general concept.

Answer 1

> Hold values, which the program will interpret and communicate.

>They store information for later use. > A word is assigned to the information by which it can be retrieved.

Question 2

Variables - In Java

Answer 2

> Different - data types based on what kind of information they will store.

Question 3

Strongly Typed Language - Java

Answer 3

> Concept used to refer to a programming language that enforces strict restrictions on intermixing of values with differing data types. When such restrictions are violated and error (exception) occurs.

> Typing in Java: allows the programming language to know with absolutely certainty that the information being stored in a variable will be ‘a certain way’.

Question 4

Data Types

Answer 4

> The types of values within a program.

Question 5

Primitive Types / Scalar types – JAVA

Answer 5

> Simple data types

> They relate to a single piece of information

Question 6

Control Structures

Answer 6

> When the program needs to make a decision:

• Decision in based on the variables given
• The control strucutre are the decision that will effect the flow of the code
• The code flow is the direction the code is being read by the computter (running program)

Question 7

Choosing which lines of code to execute and which ones to skip

Answer 7

• Dependent on the state of of the variables (the value at any given time).
• W h i l e - loop -
• Purpose: To excecute code between ‘ { } ‘ over and over until the condition becomes false.

Question 8

Data Structures - In computer Science

Answer 8

• A particular way od storing and organizing data in a computer so that it can be used efficiently
• Just a way to get around havinf to create tons of variables.

Question 9

Syntax - Concept in Computer Science

Answer 9

• Set of rules that define the combinations of symbols that are considered to be correctly structured progrmas in that language.
• Particular layout of brackets ( ), curly brackets { }, variables, indentation etc.

Question 10

Defining a variable in Java

Answer 10

1. Variable type
2. Variable’s name
3. Value of the variable
