学生人数由输入确定，动态分配内存，保存学生成绩， 然后求出学生平均成绩

#include <stdio.h>
#include <stdlib.h>
int main()
{
    int n, i, sum = 0;
    scanf("%d", &n);
    int *p = malloc(n * sizeof(int));
    if(p != NULL)
    {
        for(i = 0; i < n; i++)
        {
            scanf("%d", &p[i]);
            sum += p[i];
        }
        printf("avg is %d\n", sum / n);
        free(p);
    }
}
