A C++ Object initialized by another global variable. [on hold]

Hi I am new to C++ but I saw some code that I can not fully understand what happen.
There is a class called MyClass defined and a global variable GVar defined.
Why can you use the GVar to define a class object like this:
int GVar = 1;
const int GVar1 = 10;
MyClass testClass(GVar, GVar1);
What is happening behind the code? Does testClass constructor is called at compile time and passing (1, 10) to the constructor?
Can someone help me please?
Thanks

That is one of many ways to pass arguments to a constructor. Cant determine if it's compile time or not but probably not. This is also not the kind of question we answer here. Please see our help center for more information

If you rephrase it to be on-topic over at Stack Overflow then I believe you will find it is a duplicate. I would therefor suggest you try reading every SO question you can find under the [c++] tag about constructors, how they work, how passing arguments to constructors as well as functions works including passing rvalues and lvalues.

That is one of many ways to pass arguments to a constructor. Cant determine if it's compile time or not but probably not. This is also not the kind of question we answer here. Please see our help center for more information

If you rephrase it to be on-topic over at Stack Overflow then I believe you will find it is a duplicate. I would therefor suggest you try reading every SO question you can find under the [c++] tag about constructors, how they work, how passing arguments to constructors as well as functions works including passing rvalues and lvalues.
