main()
{
FILE *fp;int k,n;

fprintf(fp,"%d%d%d\n",a[3],a[4],a[5]);

fp=fopen("d2.dat","w"); //打开文件d2.dat为写入
fprintf(fp,"%d%d%d\n",a[0],a[1],a[2]); //将a[0],a[1],a[2]写入文件的第一行
fprintf(fp,"%d%d%d\n",a[3],a[4],a[5]); //a[3],a[4],a[5]写入文件的第二行
fclose(fp); 关闭文件
fp=fopen("d2.dat","r");//打开文件d2.dat为只读
fcanf(fp,"%d%d",&k,&n); //从文件中读取两个数字赋值给k，n（将a[0],a[1]读出）
printf("%d%d\n",k,n);打印k，n
fclose(fp);关闭文件
