What actually compiler does when we declare static variables?

Question

I want to know what actually going under the hood,how compiler treats static variables. Unlike auto variable, static variable\'s value persist even after the end of block bu

Answer 1

This code:

void function()
{
    static int var = 6;

    // Make something with this variable
    var++;
}

is internally similar to this:

int only_the_compiler_knows_this_actual_name = 6;

void function()
{
    // Make something with the variable
    only_the_compiler_knows_this_actual_name++;
}

In other words, it's a kind of "global" variable whose name, however, doesn't conflict with any other global variable.
