What is cross platform coading ?

Question

in coding I can see now a days many people are saying Corsa platform coding experts., what that means and what is the main purpose

Answer 1

Cross platform means that you can run the same code on different Operating Systems, for instance the same Java code can be run on a Windows PC, Mac or Linux PC. This reduces the development time because you only have to write code once and use it on multiple platforms. Other examples of multiplatform solutions are: Qt Framework, .net Core, Xamarin, Python, php and javascript.

Answer 2

Your written code can run on any OS(Operation System)
like windows,linux,mac,etc without any major change in your code.
