有以下程序
#include <stdio.h>
Main()
{ FILE *fp;
Int i,a[6]={1,2,3,4,5,6};
Fp=fopen("d3.dat","wb+");
Fwrite(a,sizeof(int),6,fp);
Fseek(fp,sizeof(int)*3,SEEK_SET); /*该语句使读文件的位置指针从文件头向后移动3个int型数据*/
Fread(a,sizeof(int),3,fp); fclose(fp);
For(i=0;i<6;i++) printf("%d,",a[i]);
}
程序运行后的输出结果是______。
A.4,5,6,4,5,6, B.1,2,3,4,5,6, C.4,5,6,1,2,3, D.6,5,4,3,2,1,正确答案A
