实验内容：实验指导书中的实验九。

实验步骤

9.1 调试程序，找出程序的错误。

9.2 运行程序：

9.3 修改程序错误，并运行。

9.4. 程序填空：

9.5. 程序填空：

#include

main()

{

int a[5][5]={0},*p[5],i,j;

for(i=0; i<5; i++) p[i]= &a[i][0] ;

for(i=0; i<5; i++)

{*(p[i]+ i) =1;

*(p[i]+5- (i+1)) =1;

}

for(i=0; i<5; i++)

{

for(j=0; j<5; j++)

printf("%2d", p[i][j]);

;

}

}

9.6 编程(选作)

运行结果(请帖图)：

97. 运行程序(选作)：

4、实验心得：

指针是很好的工具，是的程序更加灵活。但是在使用的时候，要注意指针使用的规则，一定要初始化指针，掌握指针的单向传递规律，辨析实参与形参之间变量传递的方向性。而且指针不能滥用
