为什么堆被损坏？不懂

#include<stdio.h>#include<stdlib.h>typedef struct clothes{ char num[20]; char name[20]; char time[30]; float price; int number; struct clothes *next;}CLO;int main() { FILE *fp1; CLO *d,*c,*head; head=0; if((fp1=fopen("D:\handclothes.txt","r"))==NULL) { printf("Failure to open clothes.txt!\n"); exit(0); } while(!feof(fp1)) { if((c=(CLO *)malloc(sizeof(CLO)))==NULL) { printf("Not able to allocate memory.\n"); exit(1); } fscanf(fp1,"%s",c->num); fscanf(fp1,"%s",c->name); fscanf(fp1,"%s",c->time); fscanf(fp1,"%f",&c->price); fscanf(fp1,"%d",&c->number); if(head==0) { head=c; d=c; } else { d->next=c; d=c; } } d->next=0; fclose(fp1); printf("%d",head->number); free(head); return 0;}

用代码块格式化一下啊，这怎么看

内存要加1

#include<stdio.h>
#include<stdlib.h>
typedef struct clothes
{   char num[20];
    char name[20];
    char time[30];
    float price;
    int number;
    struct clothes *next;
} CLO;
int main() {
    FILE *fp1;
    CLO *d,*c,*head;
    head=0;
    if((fp1=fopen("D:\handclothes.txt","r"))==NULL)
    {   printf("Failure to open clothes.txt!\n");
        exit(0);
    }
    while(!feof(fp1))
    {   if((c=(CLO *)malloc(sizeof(CLO)+1))==NULL)
        {   printf("Not able to allocate memory.\n");
            exit(1);
        }
        fscanf(fp1,"%s",c->num);
        fscanf(fp1,"%s",c->name);
        fscanf(fp1,"%s",c->time);
        fscanf(fp1,"%f",&c->price);
        fscanf(fp1,"%d",&c->number);
        if(head==0) {
            head=c;
            d=c;
        }
        else {
            d->next=c;
            d=c;
        }
    }
    d->next=0;
    fclose(fp1);
    printf("%d",head->number);
    free(head);
    return 0;
}
