return a function

[boontune]

Hi there!

Could anyone tell me how to return a function back to main()??



Cheers



ps i have looked on the boards......

[Prelude]

Use a function pointer:

#include <iostream>

typedef void (*pf)();

void print()
{
  std::cout<<"Now we're havin fun!\n";
}

pf func()
{
  return &print;
}

int main()
{
  func()(); // How's this for wacky syntax? :p
  return 0;
}

-Prelude

Then, how's this?

 
void  (*func())()
{
  return &print;
}

You can't return functions in c. You can in scheme and some other languages but not in c++.

There's stuft you can do such as returning function pointers
or function objects which are classes like

class C
{
public:
       int operator()(int n) const { printf("n = %d\n"); }
};
