ExternVariables
The extern keyword is used for declaring variable with global lifetime. These variables exist from the start of the program and memory for them is allocated and initialized immediately after the start of the program.
You can create programs that consist of multiple source files; in this case a directive to the preprocessor #include is used. Variables declared as an externwith the same type and identifier can exist in different source files of one project.
When compiling the whole project, all the externvariables with the same type and an identifier are associated with one part of memory of the global variable pool. Externvariables are useful for separate compilation of source files. Extern variables can be initialized, but only once - existence of several initialized externvariables of the same type and with the same identifier is prohibited.
• “external variable initialization is not allowed”
• “unexpected token”

You should have 1 time :
Then as much repetition in include files :
Sorry to drag this one back up again. To be clear, my best option when I want to declare an input variable that can be modified when the code runs is to pass the value of the initialized variable onto another variable?
eg
Or is there a better way to skin this cat?
