 INTRODUCTION

September 08, 2022

Good morning students and welcome to todays lesson, we are all familiar with the English  Alphabets, Numbers and Figures

So, what are:

 Alphabets ?

Numbers ?

Figures ?

SEE ANSWERS BELOW: 

 Alphabets are set of letters or symbols in a fixed order used to represent the basic set of speech sounds of a language, especially the set of letters from A to Z.

figures.

Numbers are an arithmetical value, expressed by a word, symbol, or figure, representing a particular quantity and used in counting and making calculations.

1. Figures are numbers, especially one which forms part of official statistics or relates to the financial performance of a company.
   STEP 1

   Our topic for today is input devices. 

   A data type, in programming, is a classification that specifies which type of value a variable has and what type of mathematical, relational or logical operations can be applied to it without causing an error. 

   
   

   A string, for example, is a data type that is used to classify text and an integer is a data type used to classify whole numbers.

   
   

   EXAMPLES OF DATA TYPES

   Below is a video on the differences between a float data type and an int data type with examples.

   The primary distinction between a character and a string is that a character is a single letter, number, space, punctuation mark, or symbol that may be represented on a computer, whereas a string is a collection of characters.

   
   

   The char data type in the C programming language can be used to store both character values and string values. In addition, the ASCII and Extended ASCII standards specify the characters that can be represented by a digital representation in a computer.

   
   

   Let us look at some example of  Data Types their uses and examples in the table below:

   Data Type	Used for	Example
   String	Alphanumeric characters	hello world, Alice, Bob123
   Integer	Whole numbers	7, 12, 999
   Float (floating point)	Number with a decimal point	3.15, 9.06, 00.13
   Character	Encoding text numerically	97 (in ASCII, 97 is a lower case 'a')
   Boolean	Representing logical values	TRUE, FALSE
