Types of Data

Char

• a single character
• example: such as letters, digits, or special symbols

String

• a sequence of characters grouped together. It can consist of letters, numbers, symbols, spaces, and even empty spaces
• example: ‘name’, ‘hobby’

Integer

• whole numbers, both positive and negative, without any decimal points or fractional parts
• example: 3, 1, 299

Float

• numbers that have decimal points or fractional parts
• example: 3.5, 19.2

Boolean

• only two possible values, true or false

Types of Data in Programing Langguage

C

Primitve Data Types	Derived Data Types
int Integer data type that holds whole numbers.	Arrays Collection of similar data items.
float Floating-point data type that holds decimal numbers.	Pointers Variables that store memory addresses
char Character data type that holds single characters.	Structures Collection of different data types under one name
double Double-precision floating-point data type for larger decimal numbers.
_Bool Boolean data type that holds true or false values.

C++

Primitve Data Types	Additional Data Types	Derived Data Types
int float char _Bool	bool Boolean data type that holds true or false values (not underscored like in C).	Arrays Pointers Structures (similar to C)
	long Extended size integer.
	long long Larger integer than long.
	unsigned int nsigned integer (cannot hold negative values).
	wchar_t Wide character data type for storing wide characters.

Java

Primitve Data Types	Derived Data Types
int Integer data type that holds whole numbers.	Arrays Collection of similar data items.
float Single-precision floating-point data type for decimal numbers.	Strings Sequence of characters treated as a data type.
boolean Boolean data type for true or false values.	Classes Blueprint for objects.
	Interfaces, Enumerations, etc.
