有a个学生，每个学生有b门课程的成绩。要求用户输入学生序号以后，能输出该学生的全部成绩用指针函数来实现

#include<stdio.h>

int main ()
{
	float score[][4]={{60,70,80,90},{56,89,67,88},{34,78,90,66}};
	float *search(float (*pointer)[4],int n);
	float *p;
	int i;
	int k;
	printf("enter the number of student:");
	scanf("%d",&k);
	printf("the scores of NO. %d are:\n",k);
	p = search(score,k);
	for(i = 0;i < 4;i ++)
	{
		printf("%5.2f\t",*(p + i));
	}
	printf("\n");
	return 0;
}

float *search(float(* pointer)[4],int n)
{
	float *pt;
	pt = *(pointer + n);
	return pt;
}
