            exit(0);
       }                                                      这里这里
    printf("输入物品单价,物品数量：\n");      
    pp=pn;   
     scanf("%lf%d",&pp->press,&pp->num);
     fwrite(pp,sizeof(struct pressnum),1,fp);             到这里  是不是有问题啊
     
    fclose(fp);            
}





帮忙看看啊

你这代码一坨屎呀
pp->press 明明是个float类型，你却用 %lf
以文本方式"at+"打开的文件，你却用fwrite(pp,sizeof(struct pressnum),1,fp)输入二进制信息

没诚意 ，我不解.

谢了啊，不过我发帖已经没分了，要不你去我别的贴随便打几个字我给你点数
