Static function declared but not defined in C++
c++, static-methods
Solution
In C++, `static` at global/namespace scope means the function/variable is only used in the translation unit where it is defined, not in other translation units.
Here you are trying to use a static function from a different translation unit (`Main.cpp`) than the one in which it is defined (`File.cpp`).
Remove the `static` and it should work fine.
Problem
I'm getting an error from the following code using C++. Main.cpp ``` #include "file.h" int main() { int k = GetInteger(); return 0; } ``` File.h ``` static int GetInteger(); ``` File.cpp ``` #include "file.h" static int GetInteger() { return 1; } ``` The error I get: ``` Error C2129: static function 'int GetInteger(void)' declared but not defined. ``` I've read the famous article "Organizing Code File in C and C++", but don't understand what is wrong with this code.
