constness

  [returnType] (* const [name])([arguments])

Example

int plus( const int& a, const int& b) { return a + b; }
int minus(const int& a, const int& b) { return a - b; }
int main()
{
  //Declaration
  int (*myFunction)(const int&, const int&); 
  myFunction = plus;
  std::cout << myFunction(5,3) << std::endl;
  myFunction = minus;
  std::cout << myFunction(5,3) << std::endl;
}
