几道小小的试题，请教各位了！！！

5. Please write the C expression equivalent to （a-b)2+(b-d)2+|sin(x)|/(ab-2)

9. What is the running result of the following code? (5%)
#include <stdio.h>
int change(int) ;
void main()
{
int x=9;
printf("%d, %d", x, change(x));
}
int change(int i)
{
i++;
return i++;
}
10. What is the running result of the following code? (5%)
#include <stdio.h>
void changeSeason(char *);
void main()
{
char *season[]={"Spring", "Summer", "Autumn", "Winter"};
char *ps=season[0];
changeSeason(ps);
printf("Now the season is %s", ps);
}

void changeSeason(char *p)
{
p++;
++p;
}

无语,我觉得你还是自己做,很基础的

5. 2*(a-b)+2*(b-d)+fabs(sin(x))/(a*b-2)
9. 9,10
10. Now the season is Spring

（a-b)2+(b-d)2+|sin(x)|/(ab-2) 
（a-b）*2+(b-d)*2+abs(sin(x))/(a*b-2);

2.
结果：9，10

5. Please write the C expression equivalent to （a-b)2+(b-d)2+|sin(x)|/(ab-2)
答： 2*(a-b)+(b-d)*2+fabs(sin(x))/(a*b-2)
9. What is the running result of the following code? (5%)
#include <stdio.h>
int change(int) ;
void main()
{
int x=9;
printf("%d, %d", x, change(x));
}
int change(int i)
{
i++;
return i++;
}
答： 9, 10
10. What is the running result of the following code? (5%)
#include <stdio.h>
void changeSeason(char *);
void main()
{
char *season[]={"Spring", "Summer", "Autumn", "Winter"};
char *ps=season[0];
changeSeason(ps);
printf("Now the season is %s", ps);
}

void changeSeason(char *p)
{
p++;
++p;
}
答： Now the season is ring

呵呵，最后一个弄错了，应该是Now the season is Spring
因为调用是只是将数组season[0]的首地址赋给形式参数指针p，而实参ps地址没变
