直接上代码了，注释用英文标注的，可能表示有误，是为了练习英文注释的习惯。

#include <stdio.h>/** *  import how many students in class. * *  @return the students' number. */int studentNum(){    int num;    printf("please import the student's number:\n");    scanf("%d",&num);    return num;}/** *  import the every student;'s score. * *  @param a          put student's score in a array. *  @param studentNum number of student */void importScore(int a[],int studentNum){    for (int i=0; i<studentNum; i++) {        printf("please import the %d's student's score:\n",i+1);        scanf("%d",&a[i]);    }}/** *  caculate student's score of total. * *  @param a          put student's score in a array. *  @param studentNum number of student * *  @return student's score of total. */int scoreSum(int a[],int studentNum){    int sum = 0;    for (int i=0; i<studentNum; i++) {        sum  = a[i]+sum;    }    return sum;}/** *  caculate the student's score of average. * *  @param sum        the student's score of total. *  @param studentNum number of student. */void scoreAverage(int sum,int studentNum){    int average = sum/studentNum;    printf("the student's average is %d\n",average);}int main(){    int number = studentNum();    int a[number];    int sum;    importScore(a, number);    sum = scoreSum(a, number);    scoreAverage(sum, number);}
