Self-test questions

For multiple choice questions, choose all options that apply:

1. Which of the following lines of code is/are not well-formed? Assume that the symbols are from the boost::chrono namespace.

   a. milliseconds ms = milliseconds(5) + microseconds(10);

   b. nanoseconds ns = milliseconds(5) + microseconds(10);

   c. microseconds us = milliseconds(5) + microseconds(10);

   d. seconds s = minutes(5) + microseconds(10);

2. What does the type boost::chrono::duration<std::intmax_t, boost::ratio<1, 1000000>> represent?

   a. A millisecond duration with integral representation

   b. A microsecond duration with integral representation

   c. A millisecond duration with floating point representation

   d. A nanosecond duration with integral representation

3. What are the differences between boost::timer::cpu_timer and boost::timer::auto_cpu_timer?

   a. auto_cpu_timer calls start in the constructor, cpu_timer does not

   b. auto_cpu_timer cannot be stopped and resumed

   c. auto_cpu_timer writes to an output stream at the end...
