  C language :The c language is procedural and general-purpose language that provide low-level access to system memory . C++ language : C++ language is object oriented programming language  C and C++ are both programming languages, but they have distinct differences in terms of their features, use cases, and design philosophies. Here are some key differences between C and C++: 1. **Object-Oriented Programming (OOP):**    - C: C is a procedural programming language. It focuses on procedures or functions and does not have built-in support for object-oriented programming concepts like classes and objects.    - C++: C++ is an extension of C that adds object-oriented features. It introduces classes, objects, inheritance, polymorphism, and encapsulation, allowing developers to design and structure their code in an object-oriented manner. 2. **Abstraction and Encapsulation:**    - C: C lacks the built-in mechanisms for abstraction and encapsulation provi...

 Basic difference are:  Browser : 1 browser are store a web pages  Search engine : 1 search engine are not store in web pages  Browsers and search engines are both essential components of the modern internet experience, but they serve different purposes and have distinct functionalities.

Python : Python is a simple language and syntax are Easy to understand and lot of library are Available.  Java : java are minimum time consuming And Fast language respect to python ... Python and Java are both popular programming languages, but they have distinct differences in terms of their syntax, features, use cases, and ecosystems. Here's a comparison between Python and Java: 1. **Syntax and Readability:**    - Python: Python emphasizes readability and simplicity with its clean and concise syntax. It uses indentation (whitespace) to define code blocks.    - Java: Java has a more verbose syntax with explicit curly braces to define code blocks. It places a stronger emphasis on type declarations. 2. **Type System:**    - Python: Python is dynamically typed, meaning variable types are determined at runtime. It does not require explicit type declarations.    - Java: Java is statically typed, which means variable types are declared explicitly ...
