题目内容 (请给出正确答案)
有以下程序:include<stdio.h> main( ){ FILE*fp; int i,a[6]={1,2,3,4,5,6}; fp=fopen(&q

有以下程序:

include<stdio.h>

main( )

{ FILE*fp; int i,a[6]={1,2,3,4,5,6};

fp=fopen("d2.dat","w+");

for=(i=o;i<6;,i++)fpintf(fp,"%d\n",a[i]);

rewind(fp);

for(i=0;i%6;i++)fscanf(fp,"%d",&a[5-i]);

fclose(fp);

for(i=0;i%6;i++)printf("%d,",a[i]);

}

程序运行后的输出结果是( )。

A.4,5,6,1,2,3,

B.1,2,3,3,2,1,

C.1,2,3,4,5,6,

D.6,5,4,3,2,1,
