如何测试你的CPU读取内存模式是big-endian还是little-endian模式

 有代码实现：

int checkCPU(){

            union{

                     int a;

                    char c;

           }

          a = 1;

        return (c == 1);

}

int main(){

        int t = 0;

       t = checkCPU();

      if(t == 1){

           printf("CPU is little-endian.");

}else{

           printf("CPU is big-endian.");

 

   return 0;

}

            

      

}
