Question 1

Static Variable

Answer 1

A variable that has had a memory location allocated for the entire lifetime of the run of the program.

Question 2

Sequence

Answer 2

• The order in which software instructions are carried out.

* instructions are carried out in the order they appear.

Question 3

Function/Method

Answer 3

• A common sequence of instructions.
• Can be declared as void where a return value is not required.
• If a return value is required, it’s type must be defined.

Question 4

Loop

Answer 4

Allows a statement or group of statements to be executed more than once.
Repeats a set number of times or until a condition has been met.

Question 5

Unconditional Repitition

Answer 5

The number of repititions is unknown.

Eg for loop

Question 6

Conditional Repition

Answer 6

The number of repetitions is known.

Eg while loop

Question 7

Selection

Answer 7

In a program it is possible to decide which statements to execute.
IE if or switch statement.

Question 8

If Statements

Answer 8

Allows control to branch to the execution of a set of instructions only if the condition evaluates to be true.

Question 9

If/Else Statements

Answer 9

Same as if statement but will include statements to be executed if the evaluation of the condition is FALSE.

Question 10

For Loop

Answer 10

The counter is initialised.

The end value for the counter is declared and the increment for the counter set.

Question 11

do While Loop

Answer 11

Same as while loop.
Executes at least one time.
Executes first then checks for specified loop condition.

Question 12

Nested Loop

Answer 12

A loop within a loop.

Used for more complex problems.

Question 13

Switch Statements

Answer 13

Allows multiple decisions to be affected. If relevant result in more efficient code than multiple IF statements.

Question 14

Switch- case statement

Answer 14

Control is transferred to the case statement which matches the switch variable.

Question 15

Switch-break

Answer 15

Execution proceeds until break statement transfers control out of switch structure.
A branch statement usually required after each case block unless case has no code.

Question 16

Answer 16

A command driven interface which takes input and displays output at a command line console with access to 3 basic data streams.

A window called a form is used. Objects are added to it. GUI is used to design form.

Question 18

namespace

Answer 18

Used to declare a scope that contains and stores a set of related objects.
Can be used to organise code elements and store classes and subsequently methods.

Question 19

class

Answer 19

Enables programmer to create custom types by grouping together variables of other types.

Question 20

CamelCase

Answer 20

The first letter in a compound word is capitalised.

Most languages do not allow the use of spaces in the names of functions or variables.

Question 21

assignment statements

Answer 21

Instantiate

Answer 22

Declaring a variable in C#.

Creating an instance in which data is stored.

Question 23

Method

Answer 23

A code block that contains a series of statements.

A program causes the statements to be executed by calling the method and specifying any required method arguments.

Question 24

Intelligence

Answer 24

Provides logical code elements that can be selected from a drop down menu while writing the code. Reduces time typing. Avoid typographical errors.

Question 25

Concatenation

Answer 25

Join two things together. Direct text with variables. Two or more variables to make a longer string.

Question 26

Implicit conversion/ coercion

Answer 26

The compiler will automatically convert from one data type to another data type. Defined I language core by language vendor.

Question 27

Explicit Conversion

Answer 27

Explicitly defined within the code of the developer rather than being completed by the runtime.

Question 28

Compiler

Answer 28

Software that converts programming language into machine code so that the PC can understand the program.

Question 29

Variable

Answer 29

Refers to memory address. | Creates and hold a space in the memory that is used for storing temporary data.

Question 30

Value Types

Answer 30

Value types are passed to methods by passing an exact copy of the data. Eg primitive types such as int, float, bool and char.

Question 31

Reference Types

Answer 31

An object is created in memory and the runtime deals with a reference to the object in memory.

Question 32

Arithmetic Operators

Answer 32

* + Add numbers * - Subtract numbers * * Multiply numbers * / Divide numbers * % Divide two numbers and returns remainder

Question 33

``` = Equal to += plus equal to -= minus equal to *= multiply equal to /= divide equal to %= Modulus (divide to numbers and return remainder) equal to ```

Question 34

Unary Operators

Answer 34

Used for increment or decrement value by 1.

Question 35

Increment Operator | ++

Answer 35

* Pre-increment (i++) - increments by 1 the loop executed. | * Post-increment (++I) - loop executed then increments by 1

Question 36
