Static keyword in function declaration can be missing in function definition?

Question

I want to have a static function which I declare in my .c file before defining it:

//file a.c version 1
static int foo();
...
static int foo()
{
...
}
         


        

Answer 1

As a sidenote, C++ provides a superior alternative to static. You can also use unnamed namespace here

Example,

namespace 
{  
   void f()
   {
   }
}

See these:
