/**
* @def assert(expr)
* @brief Macro to perform runtime assertions.
*
* The assert() macro shall insert diagnostics into programs; it shall expand to
* a void expression. When it is executed, if expression (which shall have a
* scalar type) is false (that is, compares equal to 0), assert() shall write
* information about the particular call that failed on stderr and shall call
* abort(). The information written about the call that failed shall include the
* text of the argument, the name of the source file, the source file line
* number, and the name of the enclosing function; the latter are, respectively,
* the values of the preprocessing * macros __FILE__ and __LINE__ and of the
* identifier __func__. Forcing a definition of the name NDEBUG, either from the
* compiler command line or with the preprocessor control statement #define
* NDEBUG ahead of the #include <assert.h> statement, shall stop assertions from
* being compiled into the program.
*
* @param expr The expression to be evaluated.
*
* @see abort
