Even though the global keyword is conventionally only used to access variables from within the same module, there are ways to use it in order to share variables between files. For example, we could take influence from PHP and create something similar to the "superglobals" variables. L7 Multi-File C Programs The procedures and global variables of a C program can be split across multiple files. Each of the files can be compiled separately, into a *.o file. Later, all the *.o files can be linked together (still using gcc) into a running program, an executable object program. 2009-09-25 · Hi, I have two files in my project. The second file has some different logic and it was seperated from the main file.

Just import the config module in all modules of your application; the module then becomes available as a global name. The declaration and any initialization should be in a code file. If the declared variable is needed across multiple code files, then it should be declared as an extern in a header file. As for const variables, you can certainly have an entire struct const, but I don't know if you can have mixed mebers in a struct (never tried). In web applications, you can make a variable global by using the app state of the application.

2021-03-19 2019-01-03 I think that the extern should be "ignored" (in fact you usually use the extern in the header file which is then included also in the c file defining it) – frarugi87 May 23 '17 at 10:14 Yes, I agree that the global variables should be put in the first file so that everyone can access it. Once the excel macro runs with a global variable’s value, the variable is the same across all the Sub procedures.

For each program, one source file (and only one source file) defines the variable. Similarly, one header file (and only one header file) should declare the variable. file3.h Global variables have file scope and static duration. Global variables have file scope (also informally called global scope or global namespace scope), which means they are visible from the point of declaration until the end of the file in which they are declared. Once declared, a global variable can be used anywhere in the file from that point onward! for global variables, it is undefined behaviour (objects must be defined only once in C++), for global constants, since they have internal linkage we’re having several independent objects created. But their order of initialisation is undefined, so it’s unspecified behaviour, Global variables are allocated within data segment of program instead of C stack.
