C++ can be a strange language. Most of the time it’s easy to work with, but occasionally you’ll get errors which take forever to debug. Take a look at the following code and write down what you think the output will be. #include <iostream> class Base { public: virtual void test(int x = 0) { [...]

In math, certain blackboard (double-barred) letters Z, N, R, etc. represent sets of numbers (integers, natural numbers, rational numbers, etc). These can be included in a LaTeX document using the \mathbb{[letter]} tag from within the math environment. Note that this requires the amssymb package to be included (ie: add \usepackage{amssymb} to the top of the [...]

If you’re adding a section to a LaTeX document which has a lot of special characters (such as code, HTML, etc), you can add it verbatim. This means that special characters (<, >, {, }, $, etc) will not be processed and will be displayed as they are. There are two ways of printing verbatim. [...]
Millisecond timer in C / C++

If you’re looking for a timer with fairly good accuracy in C or C++, you can use the functions in time.h and sys/time.h to build a millisecond timer. This is useful for things like evaluating the execution time of a program, roughly accurate to the nearest microsecond. double get_time_ms() { struct timeval t; gettimeofday(&t, NULL); [...]

For example: Michelangelo’s statue of David is one of the best known sculptures of the [...]
