/**
 * @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
