[c language] output the average score and the student data below or equal to the average score with the structure

1、 subject

Student records consist of names and grades , Enter... In the main function 4 Data on students , Please write a function to calculate and return the average score output , And save and output the data of students whose scores are lower than or equal to the average through the structure pointer .

requirement ：

1. Use structure ：

typedef struct Student 
{
    
	char name[20]; 
	int score; 
}Stu;

2. Use sub functions ：float StructAvg(Stu *a,Stu *b,int n,int *m)
3. To output in the main function .

Input format ： Input in sequence 4 Names and scores of students

Output format ： Save and output the data of students whose scores are lower than or equal to the average

Examples ：

Input ：
KOBE 90
YAO 90
HC 80
JAMES 70
Output ：
Avg=82.5
HC 80
JAMES 70

#include <stdio.h>
#define N 4
typedef struct Student {
    
    char name[20];
    int score;
}Stu;
float StructAvg(Stu* a, Stu* b, int n, int* m)
{
    
    int i, j = 0, sum = 0;
    float avg;
    for (i = 0; i < n; i++)
        sum += a[i].score;
    avg = sum * 1.0 / n;
    for (i = 0; i < n; i++)
        if (a[i].score < avg)
            b[j++] = a[i];
    *m = j;
    return avg;
}
int main()
{
    
    int i, j, n;
    float ave;
    struct Student s[N];
    for (i = 0; i < N; i++) {
    
        scanf("%s %d", s[i].name, &s[i].score);
    }
    struct Student h[N];
    ave = StructAvg(s, h, N, &n);
    printf("Avg=%.1f\n", ave);
    for (i = 0; i < n; i++)
        printf("%s %d\n", h[i].name, h[i].score);
    printf("\n");
