To make a variable, any variable, global to all functions in a .cpp file,
simply declare it ouside of any function.

To make a variable, any variable, global to all compiliation units (other
..cpp files as well) in a header file, or other means, declare the varaible
as extern and then in one, and only one, .cpp file declare the variable
normally.

(Untested code)

MyProg.cpp:

int proba[5]
int* probb;

void Foo()
{
   // Foo can "see" proba and probb
}

int main()
{
   probb = new int[10];

   // main can "see" proba and probb
}

-----------------------------------------

MyOtherFile.cpp:

extern* probb;

void Bar()
{
   // Bar can "see" probb, but not proba.
}
