Data Types in C++

In C++, data types are used to define variables and functions. The data type of a variable determines the size and type of data that can be stored in it. C++ supports a variety of data types, including integers, floating-point numbers, characters, and Boolean values.

Integer Data Types

Integers are whole numbers without decimal points. In C++, there are several types of integer data types available:

char: used to store single characters
short: used to store small integers
int: used to store integers
long: used to store large integers
long long: used to store very large integers
Floating-Point Data Types

Floating-point data types are used to store numbers with decimal points. In C++, there are two types of floating-point data types available:

float: used to store single-precision floating-point numbers
double: used to store double-precision floating-point numbers
Character Data Type

The char data type is used to store a single character. Characters are enclosed in single quotes, such as 'a', 'b', 'c', etc.

Boolean Data Type

The Boolean data type is used to store true or false values. In C++, the keywords true and false are used to represent these values.

Examples:

Here are some examples of how to declare variables using the different data types in C++:

// Integer data types
char myChar = 'a';
short myShort = 10;
int myInt = 100;
long myLong = 1000000;
long long myLongLong = 1000000000;

// Floating-point data types
float myFloat = 3.14f;
double myDouble = 3.14159265359;

// Character data type
char myChar = 'a';

// Boolean data type
bool myBool = true;

Conclusion:

In summary, C++ supports a variety of data types that can be used to define variables and functions. These include integer data types, floating-point data types, character data types, and Boolean data types. Understanding the different data types available in C++ is important for writing efficient and effective code.
