#include <stdio.h>
#include <stdlib.h>

struct st {
int x:1;
};

int main(void)
{
struct st s;

s.x = 1;
printf("s.x = %d\n", s.x);

exit(0);
}

维什么结果不是1呢

#include <stdio.h>
#include <stdlib.h>

struct st {
int x:2;/*改为2*/
};

int main(void)
{
struct st s;

s.x = 1;
printf("s.x = %d\n", s.x);

exit(0);
}

thank you very much

或者改为:
#include <stdio.h>
#include <stdlib.h>

struct st {
unsigned int x:1;/*改为unsigned int 形,保证没有符号位*/
};

int main(void)
{
struct st s;

s.x=1;
printf("s.x = %d\n", s.x);
getch();
exit(0);
}
