What is C++ programming language?
What is C++ programming language?
C++ is a general-purpose programming language created by Bjarne Stroustrup in 1983. It is an extension of the C programming language, and is often used for developing large and complex software applications, such as operating systems, video games, and simulations. C++ is a compiled language, which means that the code written in C++ is translated into machine code that can be directly executed by…

Data types in Java:-
This tutorial is explain about how many types Data Types in Java explanation of Primitive type and Non Primitive type with example of Java Programming.
Data type divided into two groups:-
Primitive type:- Primitive data type is predefined in java. This is always contains a value and always star with lowercase. Size of primitive data depends on data types. Example:-byte,short,long,int,float, double,boolean and char
Non Primitive Type:- This data types is created by the programmer is not defined by JAVA. This is used to call a methods to perform a operations. This data types is declare as null type value. Non Primitive Type data types start with uppercase letter. Its size has same. Examples:- String , array and Classes.

What are the Different Data Types in JavaScript
New Post has been published on https://www.codesolutionstuff.com/what-are-the-different-data-types-in-javascript/
What are the Different Data Types in JavaScript
A web scripting language is called JavaScript. It contains its own data types, much like any other computer language. The type of data that a variable can carry is defined by its data type in a language.
There are eight basic data types in JavaScript.
Data TypesDescriptionExampleStringRepresents textual datalet str = ‘Hi’, let str2 = “Hello”, let str3 = `Hello World`NumberAn integer or a floating-point numberlet num = 3, let num2 = 3.234, let num3 = 3e-2BigIntAn integer with arbitrary precisionlet num = 900719925124740999n, let num = 1nBooleanAny of two values: true or falselet flag = trueundefinedA data type whose variable is not initializedlet a;nullDenotes a null valuelet a = null;SymbolData type whose instances are unique and immutablelet value = Symbol(‘hello’);Objectkey-value pairs of collection of datalet student = ;
Table – Different Data Types in JavaScript
String
Text is stored in strings. Strings in JavaScript are enclosed in quotes:
Single quotes: ‘Hello’
Double quotes: “Hello”
Backticks: `Hello`
Example::
// Strings const firstName = "Code"; const lastName = "Solution"; const result = `Name: $firstName $lastName`; console.log(result); // Name: Code Solution
Number
Numerals represent floating-point and integer numbers (decimals and exponentials). Additionally, a number type can be +Infinity, -Infinity, or NaN. (not a number).
const number1 = 3; const number2 = 3.433; const number3 = 3e5; // 3 * 10^5 const number4 = 3 / 0; console.log(number4); // Infinity const number5 = -3 / 0; console.log(number5); // -Infinity // strings can't be divided by numbers const number6 = "abc" / 3; console.log(number6); // NaN
BigInt
Only numbers less than and greater than -(2sup>53/sup> -1) can be represented using the Number type in JavaScript. However, you can use the BigInt data type if you require a larger number than that.
By adding n to the end of an integer, a BigInt number is produced.
// BigInt value const num1 = 900719925124740998n; const num2 = 900719925124740998n; const num3 = 10; // Adding two big integers const result1 = num1 + num2; console.log(result1); // "1801439850249481996n" // Error! BitInt and number cannot be added const result2 = num1 + num2 + num3; console.log(result2); // Uncaught TypeError: Cannot mix BigInt and other types
Boolean
This data type represents logical entities. Boolean values can only be either true or false.
const dataChecked = true; const valueCounted = false;
undefined
A value that is not assigned is represented by the undefined data type. A variable’s value will be undefined if it is declared but its value is not yet assigned.
let name; console.log(name); // undefined let name = undefined; console.log(name); // undefined
null
Null is a special value in JavaScript that denotes an empty or undefined value.
const number = null;
Symbol
Symbol values can be defined as values with the data type Symbol. Symbol is a singular, immutable primitive value.
// Two symbols with the same description const value1 = Symbol('hello'); const value2 = Symbol('hello'); let result = (value1 === value2) ? true : false; // false; // Note: Though value1 and value2 both contain 'hello', they are different as they are of the Symbol type.
Object
A complicated data type called an object enables us to store data collections.
