帮忙这程序错在哪

#include <stdio.h>
#include <stdlib.h>

typedef struct t_student {
unsigned id;
float mid_term_score;
float end_term_score;
float average_score;
} STUDENT;

int main()
{
unsigned stu_numbers=0;
unsigned i;

printf("Please input numbers of the students: ");
scanf("%d", &stu_numbers);

STUDENT *p_stu = (STUDENT*) malloc( stu_numbers*sizeof(STUDENT) );
if(!p_stu)
printf("\nMemery ERROR !\n");

for(i=0; i<stu_numbers; i++)
{
printf("\nPlease input the id of student %d : ", i+1);
scanf("%d", &( (p_stu+i)->id ));
printf("Please input the mid_term_score of student %d : ", i+1);
scanf("%f", &( (p_stu+i)->mid_term_score ));
printf("Please input the end_term_score of student %d : ", i+1);
