Then write +just enough code to get the test to pass. Once you've done that, +uncomment the next test by moving the following line past the next test. + +```C++ +#if defined(EXERCISM_RUN_ALL_TESTS) +``` + +This may result in compile errors as new constructs may be invoked that +you haven't yet declared or defined. Again, fix the compile errors minimally +to get a failing test, then change the code minimally to pass the test, +refactor your implementation for readability and expressiveness and then +go on to the next test. + +Try to use standard C++11 facilities in preference to writing your own +low-level algorithms or facilities by hand.
