Getting ready

For this recipe, we require three files. The first is the implementation that we wish to test (we can call the file leaky_implementation.cpp):

#include "leaky_implementation.hpp"int do_some_work() {  // we allocate an array  double *my_array = new double[1000];  // do some work  // ...  // we forget to deallocate it  // delete[] my_array;  return 0;}

We also need the corresponding header file (leaky_implementation.hpp):

#pragma onceint do_some_work();

And, we need the test file (test.cpp):

#include "leaky_implementation.hpp"int main() {  int return_code = do_some_work();  return return_code;}

We expect the test to pass, since the return_code is hardcoded to 0. However, we also hope to detect a memory leak, since we forgot to de-allocate ...
