#include <stdio.h>
static int test;
int main () {
    return 0;
}

and after i compiled the file and check the size of bss segment nothing changed.

here’s the ouput of the terminal after i check the bss segment size before adding the uninitialized static variable

C:UsersUserDocumentsProgrammingC>size a.exe
   text    data     bss     dec     hex filename
  14584    2556     480   17620    44d4 a.exe  

here’s the ouput after i compiled with the uninitialized static var.

C:UsersUserDocumentsProgrammingC>gcc test_static.c

C:UsersUserDocumentsProgrammingC>size a.exe        
   text    data     bss     dec     hex filename
  14584    2556     480   17620    44d4 a.exe   

ps. please teach me and correct my mistakes. im trying to learn c and i also want to learn what is happening behind the scene of the computer that is why im doing this…

i tried checking the data segment when i compiled the file with initialized static variable and it is adding up to the data segment which is working, but still the uninitialized static variable is not adding up to the bss
