程序代码：

void print_1()
{

    FILE *fp;
    if((fp=fopen("jiangpai.txt","rb"))==NULL)
    {
    printf("cannot open file\n");
    return ;
    }
    printf("编号\t国家\t金牌\t银牌\t铜牌\t奖牌数\n");
    while(fread(&mm,sizeof(struct MM),1,fp)==1) 
    printf("%d\t%s\t%d\t%d\t%d\t%d\t\n",mm.num,mm.nation,mm.gold,mm.silver,mm.brown,mm.gold+mm.silver+mm.brown);
    fclose(fp);
}
