I\'m getting an error from the following code using C++.
Main.cpp
#include \"file.h\"
int main()
{
int k = GetInteger();
retu
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.
