C / C++ / MFC

Hoping for some program to translate a C program (in the sense "an arbitrary C program") into a state machine is naively optimistic.

Quote:

What you can do is to provide a framework for editing the FSM as a FSM, and let the developer specify the actions of each individual transition within that framework. Then, the framework can lay out the code for each transition (as well as the common logic for the state transitions themselves).

This is actually one of my current pet projects. Maybe I will write a CP article about it some day. It is far from ready yet, but if you would like to discuss it directly with me, send me an email. Maybe that could help pushing my hobby project forward

can pass a vector <string> by reference or have been told to define "local vector" and "return" if from the function.

vector <int> get_rand_vect(size_t size)
{
  vector <int> v;
  while (size--)
  {
    v.push_back(rand());
  }
  return v; // this is optimized by the compiler
}

That would not work in my function which retrieves unknown "size" of (string) data.

#include <iostream>
#include <vector>

using namespace std;


vector <int> get_a_fresh_vector_with_unknown_size()
{
  vector <int> v;
  int N = rand() % 128;

  for (int n = 0; n < N; ++n)
    v.push_back( rand() );

  return v;
}


int main()
{
  auto v =  get_a_fresh_vector_with_unknown_size();
  for (auto x : v)
    cout << x << " ";
  cout << endl;
}
