C99 introduced a number of new attributes, like inline functions, several new information styles (which include lengthy extended int and a fancy variety to signify elaborate figures), variable-size arrays and flexible array associates, improved assistance for IEEE 754 floating issue, guidance for variadic macros (macros of variable arity), and assist for a person-line comments beginning with //, as in BCPL or C++. Quite a few of those had previously been carried out as extensions in numerous C compilers.
Due to the fact arrays are always accessed (in impact) by way of pointers, array accesses are generally not checked in opposition to the underlying array dimension, Whilst some compilers may give bounds checking as a possibility.
