C语言中u8,u16,u32的详解

一、代表意思

 1、u8 :无符号char字符类型

2、u16:无符号short短整形

3、u32:无符号int整数leixing

 二、举个例子


typedef   signed  char         int8_t;  //  标准表达方式 signed char 被等同于 int8_t;
typedef   signed short int     int16_t;
typedef   signed  int          int32_t;//在32位环境里,int代表4个字节32位!!
typedef   signed __int64       int64_t;
 
typedef   unsigned char         uint8_t;
typedef   unsigned short int    uint16_t;
typedef   unsigned int          uint32_t;
typedef   unsigned  __int64     uint64_t;
 
typedef   uint32_t   u32;///32位
typedef   uint16_t   u16;///16位
typedef   uint8_t     u8;///8位
