#include <stdio.h>

#define UDLONG unsigned long long
#define ULONG unsigned long
#define BYTE unsigned char
#define UINT unsigned int
#define UWORD unsigned short

void main(void)
{
    BYTE a=1;
    UWORD aa;
    UINT b=1;
    UINT bb;
    UDLONG c=1;
    UDLONG cc;
    aa=a<<8;
    bb=b<<32;
    cc=c<<64;
}

环境：vs2008
结果：aa=256 bb=1 cc=0
求解释

照你所说b<<32和c<<64均已超过最大可能位移数 为什么两者结果不一致
