C ++中类似python的字符串索引

Question

Is there any (possibly, using a macros) way to get a substring of a string using python-like expression f(i:j)? Or, more specifically, resolve i:j expression into pair of indices i and j? Any ideas?

EDIT: Yes, I need :. Or ;. Basically, something that simple function or macros can't do. Just want to see if it is possible or not.

EDIT: Basically, I want to see if it is widely applicable. For arrays as well, maybe. So the question is more of a "Can I turn i:j to ij", I guess. Doesn't matter is these are std:strings or c-strings.

Answer 1

I hate myself for answering, but ...

#include <iostream>
#include <string>

#define f(x) substr(true?x, false?x)

int main () {
  std::string s = "Hello, world";
  std::string y = s.f(1:4);
  std::cout << y << "\n";
}
