is it possible in C or C++ to create a function inside another?

Question

Could someone please tell me if this is possible in C or C++?

void fun_a();
//int fun_b();
...
main(){
   ...
   fun_a();
   ...
   int fun_b(){
     ...

The term you're looking for is nested function. Neither standard C nor C++ allow nested functions, but GNU C allows it as an extension. Here is a good wikipedia article on the subject.
