Question

c语言怎么把一个十六位数据拆成两个八位，怎么把两个八位数据合成十六位？

Answer 1

比如将十六进制数“正橘2A12”举袭团拆成"2A"和"12"禅衫,然
后再把"2A"和"12"对调位置合成"122A"
#include<stdio.h>
main()
{
int a=0x2a12;
char b,c;
b=a>>8;
c=a&0x0ff;
printf("%x,%x",b,c);
a=(c<<8)|b;
printf("\n%x",a);
return 0;
}

Answer 2

unsigned short a = 0xA4F5;
unsigned char b = (a & 0xFF00)>者御>8;
unsigned char c = a & 0x00FF;
unsigned short d = (b<<首塌岩衫巧8) | c;
