int	Integer : like char int, signed int, unsigned int, short int, long int, long long int ... int64_t : 64bit의 signed int uint_fast_16_t : unsigned integer with 8bits int_least32_t : signed integer with at least 32bits ( like int ) Literals
float double	floating-point types. float, double, long doube Literals
