The inline function contains static variables and whether multiple copies are generated during the call.

Inline int static_test ()
{
Static int I = 0;
...
}
Inline indicates the compile timeCodeCopy, there are multiple copies, but in the VC test, I only have one copy, then how the compiler implements:

 

1. Copying code is not necessarily a copy of C code. It can be a copy of compiled assembly code. While the function is in the code segment, the variable is in the data segment. Only the function part is copied. Static variables only store the address of the variable in the function section.

2. Static variables are not stored in the stack, but in the static data zone. They are stored together with global variables. They cannot be confused with local variables.
