为什么这里的&st.wDay 收不到 数据呢？？
[解决办法]
scanf("%d%d%d%d%d%d%d%d",
都是数字你怎么输入呢？
要改成这样：
scanf("%d,%d,%d,%d,%d,%d,%d,%d",输入类似2000,1,1,0,0,0,0,0
[解决办法]
看了一下SYSTEMTIME的定义，所有成员都是WORD类型的，%d要求参数是int，参数不匹配结果未知
要定义临时的int变量才可以
int tmpData[8];
scanf("%d,%d,%d,%d,%d,%d,%d,%d",tmpData[0],tmpData[1]...,tmpData[8])
然后
st.wYear =tmpData[0];
st.wMonth=tmpData[1];
.....
这样应该就可以了
