程序代码：

#include <stdio.h>

int main(int argc, char *argv[])
{
    float score[][4]={{60,70,80,90},{92,85,75,65},{65,70,85,90},{85,95,75,60}};
    float *search(float(*pointer)[4],int n);
    float *p;
    int i,m;
    printf("enter the number of student:");
    scanf("%d",&m);
   
    printf("The Scores of No.%d are:\n",m);
    p=search(score,m);
    for(i=0;i<4;i++)
    {
        printf("%5.2f\t",*(p+i));  
    }
}

    float *search(float(*pointer)[4],int n)
    {
        float *pt;
        pt= pointer+n;  //我这样写的,书上是pt=*(pointer+n)，都编译正确,请问这怎么解释？
        return(pt);
    }
