int16_t uint32_t int_least8_t intmax_t如何输出？

int16_t uint32_t int_least8_t intmax_t这些类型的占位符是什么？是不是有相同位的占位符就可以使用去输出？

printf("%lld",A);

sizeof(A) format
2 %hd
4 %d
8 %ld
16 %lld

听说这个有用 The following are typedefs of fundamental integral types or extended integral types. signed type unsigned type description intmax_t uintmax_t Integer type with the maximum width supported. int8_t uint8_t Integer type with a width of exactly 8, 16, 32, or 64 bits. For signed types, negative values are represented using 2's complement. No padding bits. Optional: These typedefs are not defined if no types with such characteristics exist.* int16_t uint16_t int32_t uint32_t int64_t uint64_t int_least8_t uint_least8_t Integer type with a minimum of 8, 16, 32, or 64 bits. No other integer type exists with lesser size and at least the specified width. int_least16_t uint_least16_t int_least32_t uint_least32_t int_least64_t uint_least64_t int_fast8_t uint_fast8_t Integer type with a minimum of 8, 16, 32, or 64 bits. At least as fast as any other integer type with at least the specified width. int_fast16_t uint_fast16_t int_fast32_t uint_fast32_t int_fast64_t uint_fast64_t intptr_t uintptr_t Integer type capable of holding a value converted from a void pointer and then be converted back to that type with a value that compares equal to the original pointer. Optional: These typedefs may not be defined in some library implementations.* Some of these typedefs may denote the same types. Therefore, function overloads should not rely on these being different. * Notice that some types are optional (and thus, with no portability guarantees). A particular library implementation may also define additional types with other widths supported by its system. In any case, if either the signed or the unsigned version is defined, both the signed and unsigned versions are defined.

简单来说，uint8_t / uint16_t / uint32_t /uint64_t这些数据类型都只是别名而来，具体如下：一、C语言数据基本类型在C语言中有6种基本数据类型：short、int、long、float、double、char 1）整型：short int、int、long int 2）浮点型：float、double 3）字符类型：char 二、分析uint8_...
