From the QnA for what a runtime is : What is "runtime"?
从QnA来看运行时是什么：什么是“运行时”？
I understood about runtime a little. To make my understanding more robust, I'd like to ask new question.
我对运行时有点了解。为了让我的理解更加强大，我想问一个新问题。
Is C runtime an essential for any other programs like lua, haskell, java, etc... ?
C运行时是否适用于任何其他程序，如lua，haskell，java等......？
I know C library implements not only standard C api but also system call wrappers also.
我知道C库不仅实现了标准的C api，还实现了系统调用包装器。
And I know lua runtime is no different than just a C program. This means lua runtime is based on C runtime.
我知道lua运行时与C程序没有区别。这意味着lua运行时基于C运行时。
So I guess any other language would be in the same situation. Because it is only C rumtime which can call system calls.
所以我猜任何其他语言都会出现同样的情况。因为只有C朗姆酒可以拨打系统电话。
I considered for linux but I guess Windows and other Unix implementations must be same.
我考虑过linux，但我猜Windows和其他Unix实现必须相同。
Am I right?
我对吗？

Not necessarily.
不必要。
All programs written in C make use of the C runtime environment, be it the standard library, the stuff happening before the main function, or else.
用C编写的所有程序都使用C运行时环境，无论是标准库，还是主函数之前发生的事情，或者其他。
If a compiler/interpreter/virtual machine is written in C, yes, it does make use of the C runtime.
OTOH, if it isn't, it does not.
如果编译器/解释器/虚拟机是用C编写的，是的，它确实使用了C运行时。 OTOH，如果不是，它不会。
Note that you have to go up the whole "compiler/interpreter/virtual machine chain."
A Python interpreter written in Haskell might still indirectly rely on the C runtime environment if the Haskell interpreter has been written in C.
请注意，您必须完成整个“编译器/解释器/虚拟机链”。如果Haskell解释器是用C编写的，那么用Haskell编写的Python解释器可能仍然间接依赖于C运行时环境。
[...] it is only C rumtime [sic] which can call system calls.
[...]只有C rumtime [原文如此]可以调用系统调用。
No. The C runtime provides wrappers around some system calls. You can write programs in pure assembly making use of system calls and not rely on the C runtime library at all.
否.C运行时提供了一些系统调用的包装器。您可以使用系统调用以纯汇编编写程序，而不是完全依赖C运行时库。
