i'm trying understand ways in c global variable can shared between multiple files (compilation units). i've read excellent question , answer here . after doing few tests i'm still left stuff don't get: basically question be: if there's variable declared (but not defined) in header without extern keyword, ok include header in various compilation units in order make available variable compilation units? in scenario it's implied 1 (and one) compilation unit contains code initializing (defining?) variable, , called first before other compilation units try variable. if true, procedure what's called "implicit extern" ? i'll illustrate question example: header "mycommonheader.h" contains: //mycommonheader.h int* i; //pointer int file myfirstheader.h contains: //myfirstheader.h void changeit(int newvalue); file myfirstsource.c contains: //myfirstsource.c #include "myfirstheader.h" void changeit(int newvalue) {...
