Once in a while so it happens that a programmer wishes to time his own creation. This article presents a simple and portable implementation of a Timer class which saves the time of its creation and computes the time it took until destruction, effectively measuring the runtime spent in the enclosing scope.
The classes istringstream & ostringstream can be utilized to create generic, templated, toString() & fromString() functions. This functionality (which is built-in in many languages, such as Java) may come in very handy, quite often.
