下面的程序该怎么改？

[wangbin995]

#include <stdio.h>
float *FindRow (float (*pp)[4], int j);
int main()
{
float score[][4] =
{{18.87,8.83,8.64,8.91},
{12.11,12.23,12.34,12.20},
{30.44,30.66,30.58,30.4},
{20.12,20.08,20.21,20.66}};
float *p;
int i, n = 2;
printf ("The record of No. %d are: \n", n);
p = FindRow (score, n);
for (i = 0; i < 4; i++)
{
printf("%5.2f\t", *(p+i));;
}
return (0);
}

float *FindRow(float (*pp)[4], int j)
{
float *pt;
pt = *(pp+j);
return pt;
}

printf("%5.2f\t", *(p+i));; 
改
printf("%5.2f\t", *(p+i));

如果还不行。应该是编译器的问题！

.\c2是啥？？

vc6上编译没有错误，只有警告~

运行结果：
The record of No. 2 are:
30.44 30.66 30.58 30.40 Press any key to continue

c默认的浮点数是double 注意下格式就好了

那里是我多打了个“；”，去掉之后还是有这些问题

3楼的兄弟找到了原因，学习了。

to coding_hello :我的文件名字起错了的，忘记带.c了，至于那些警告，3楼的帮我解决了。
