C99 released a number of new characteristics, including inline capabilities, numerous new details sorts (which includes extensive extended int and a posh variety to represent complicated quantities), variable-size arrays and versatile array members, improved assist for IEEE 754 floating point, help for variadic macros (macros of variable arity), and assist for a person-line reviews beginning with //, as in BCPL or C++. Numerous of such had by now been applied as extensions in quite a few C compilers.
