Computer Science Programming Basics - Data Types

?
The five main data types of programming languages
Integer, Real, Boolean, Character and String
1 of 22
The characteristic of this data type is whole numbers only
Integer
2 of 22
The characteristic of this data type is numbers that have a decimal part
Real
3 of 22
The characteristic of this data type is can only take one or two values
Boolean
4 of 22
The characteristic of this data type is a single letter, number or symbol
Character
5 of 22
The characteristic of this data type is used to represent text in a collection of characters
String
6 of 22
The typical amount of memory taken up by this data type is 2 or 4 bytes
Integer
7 of 22
The typical amount of memory taken up by this data type is 4 or 8 bytes
Real
8 of 22
The typical amount of memory taken up by this data type is 1 bit but usually 1 byte
Boolean
9 of 22
The typical amount of memory taken up by this data type is 1 byte
Character
10 of 22
The typical amount of memory taken up by this data type is 1 byte for each character
String
11 of 22
Using the correct data types helps the code with this
Memory efficiency, robust and predictability
12 of 22
Weakly typed languages can lead to this
Unpredictable results and less errors
13 of 22
Strongly types languages can lead to this
Predictable results but more errors
14 of 22
This is used to change the data type
Casting
15 of 22
Definition of casting
Manually converting between data types
16 of 22
You can use the ASC() and CHR() functions to find this
The ASCII number
17 of 22
This data type should be used to store the initial of a first name
Character
18 of 22
This data type should be used to store a surname
String
19 of 22
This data type should be used to store an age
Integer
20 of 22
This data type should be used to store a height
Real
21 of 22
This data type should be used to store male or female
Boolean
22 of 22
