判断大小端

题目：你的电脑存储方式是大端存储还是小端存储

<span style="font-family:Microsoft YaHei;font-size:18px;">//判断大小端#include <stdio.h>#include<stdlib.h>int main(){//union w//{//int a;  //4 bytes//char b; //1 byte//} c;//c.a = 1;//if (c.b == 1)//printf("It is Little_endian!\n");//else//printf("It is Big_endian!\n");//system("pause");int a = 0x01;char * p = (char*)& a;if (*p == 1){printf("little endian\n");}else{printf("big endian\n");}system("pause");return 0;}</span>

正如上图所示，小端模式下的存储方式：高地址存放高位数据，低地址存放低位数据
