intN_t:宽度恰好为 N 位的带符号整型,如int32_t。 int_fastN_t:宽度至少有 N 位的最快的带符号整型。 int_leastN_t:宽度至少有 N 位的最小的带符号整型。 无符号版本只需在有符号版本前加一个 u 即可,如uint32_t。 INT32_MAX和INT32_MIN分别为int32_t的最大值和最小值。 注意:混用定宽整数...

On any given platform, by the definition of uint_least32_t, the width of type char32_t can be greater than 32 bits, but the actual values stored in an object of type char32_t will always have a width of 32 bits. Example Run this code #include <stdio.h> #include <uchar.h> in...
