Stuff We Didn’t Cover
static
member data
static
members of a class are not associated with objects that are instances of the class
but instead there is one value for all instances of the class. In this sense, they act as
global data in the class’s namespace.
Memory management
We’ve been relying mainly on objects that manage their own memory
internally (like std::vector
). We saw one instance of allocating memory
on our own using new
or by make_unique
. The latter is the safest way
to deal with allocating memory.
Regular expressions
Regular expressions are a powerful way to search for patterns and extract substrings out of strings. The C++ regular expressions library provides all the capability needed to work with regular expressions.
Profiling
A profiler will allow you to time independent functions or even lines of code and generate a report telling you where your code spends most of its time.
GNU gprof is the GNU profiler
than can be used with g++
.
