is c++ related with html ?

Answer 1

C++ is a compiled, object-oriented programming language. When C++ is compiled, it can become an application. This application is often executed by an operating system. Or, maybe the operating system runs in C++, too. Web browsers are written in C++.

HTML isn't a programming language. It's a markup language. HTML is used to mark upcontent. Web pages are frequently written in HTML. Web browsers will parse the HTML. If that browser uses JavaScript, it will parse the HTML and interpret the content with a JavaScript engine creating a Document Object Model. The DOM is a JavaScript interpretation of your HTML document (with plenty more added goodies, of course)

so both are different languages C++ for app development
html is for web development

Answer 2

Answer 3

thank you a lot for information

Answer 4

c uses compiler to run its program and it's not web language while HTML is translated by browser by converting it into DOM object and web language.
