What are the differences between different versions of compilers?

Question

C++ / C#

Have a nice day everyone.
I asked myself a serious question when working with C ++ - the choice of compiler version.
What are the differences?
Basically, the question is because of universities, because. from idleness I wrote coursework on OOP in C ++, and there were problems (I have VSC 2013, and students have VC ++ 2006) due to syntax errors and other things. Should I choose the same way as with Java\C# (higher is better) ?.
What points should be considered when choosing if I'm going to cross-platform?
At the same time, should I somehow worry if, for example, I write C ++ under UnrealEngine4? That is, does the principle "it is enough to know how software development works to write in any PL" work here?

Answer 1

1) See the differences in the descriptions for the releases. They always write there that they fixed / added / removed.
2) For cross-platform, compile with -pedantic -Wall -Wextra flags (the studio should have similar flags).
3) The newer the compiler, the better: more optimizations, bug fixes (yes, and new bugs), support for features from new C++ standards, etc.
4) Yes, it is enough to understand how to develop software and be able to do it. The language is just a tool, but it affects the efficiency of development. Incl. mastery of the instrument is also necessary.
