C++内存对齐问题。。。。出现了意想不到的结果

[jk2niya]

#include <stdio.h>

typedef union{
long i;
int k[5];
char c;
}DATE;

struct data
{
char c;
int cat;
DATE cow;
double dog;
}too2;

struct data1
{
char c;
int cat;
double dog;
}too;

void main(){

DATE max;
printf("%d\n",sizeof(max));
printf("%d\n",sizeof(too));
printf("%d\n",sizeof(too3));
printf("%d",sizeof(too2));

}
结果是：
20
16
32
40
难道too3 中的 char c占8个字节？？？？？

where is too3?

没有too3....而且居然到现在还能见到void main的写法......
