(C++) boost::function

Example using boost::function and plain function pointers

include <cassert>

include <boost/function.hpp>


int func1(const int& x)
{
  return x;
}
int func2(const int& x)
{
  return x*x;
}
int main()
{
  //Using boost::function
  boost::function1<int,const int&> f; //boost::function1 as function takes only 1 argument
  f = func1;
  assert(f(3)==3);
  f = func2;
  assert(f(4)==16);
  //Using function pointers
  int(*pFunc)(const int&);
  pFunc = func1;
  assert(pFunc(3)==3);
  pFunc = func2;
  assert(pFunc(4)==16);
}
