3个学生，各学4门课，计算总平均分数以及第n个学生的成绩(用指向数组的指针作函数参数)

#include<stdio.h>

int main()
{
void average(float *p,int n);
void search(float (*p)[4],int n);
float score[3][4] = {{65,67,70,60},{80,87,90,81},{90,99,100,98}};
average(*score,12);
search(score,2);
return 0;
}

void average(float *p,int n)
{
float *p_end;
float sum = 0;
float aver;
p_end = p+n-1;
for(;p <= p_end;p++)
{
sum = sum+(*p);
}
aver = sum/n;
printf("average = %5.2f\n",aver);
}

void search(float (*p)[4],int n)
{
int i;
printf("the score of NO.%d are:\n",n);
for(i = 0;i <4;i++)
{
printf("%5.2f\n",*(*(p+n)+i));
}
printf("\n");
}
