Answer 1

Can I take a look at your program?

Answer 2

The issue you mention is called "portability."

 

For example, Java provides portability by compiling all Java source code into Java Byte Code to run on the JVM (Java Virtual Machine) that is tailored to the computer and operating system on which it is run.  The JVM is standardized.

 

Often, computer languages differ on how they handle uninitialized variables, default variable size, and other computer language features.  Also, there are various versions of languages.  You may have noticed that Internet Explorer often produces different results than Firefox or Chrome.

 

HackerRank supports 15+ domains and 35+ languages.  A typical PC supports only a few.  Since you wrote a simple program, PLZ post it on this forum.
