Initialization of objects in C ++

Question

I want to know, in C ++, when do objects initialize?
Is this compilation time or link time?
For example:

//file1.cpp
extern int i;
int j=5;

//file2.cpp ( link with file1.cpp)
extern j;
int i=10;  

Now, what the compiler does: for me, it allocates memory for variables.
Now I want to know:
does it add an initialization value in this repository or is it executed during the connection?
