#include<stdio.h>
#include<math.h>
#include<stdlib.h>
#include<string.h>
#define N 3
void aver(int scores[][N],int* credit)
{
    int i,j;
    float sum1,sum2=0;
    for(i=0;i<N;i++)
        sum2+=credit[i];

    for(i=0;1<4;i++)
    {
        sum1=0;
        for(j=0;j<N;j++)
            sum1+=scores[i][j];
        printf("第%d个学生的加权平均成绩为：%.2fn",i+1,sum1/sum2);
    }
}

int main()
{
    int scores[4][N]={{82,98,72},{94,64,83},{68,83,95},{79,76,86}};
    int credit[N]={3,4,2};
    void aver(int (*)[N],int*);
    aver(scores,credit);
    system("pause");
    return 0;
