有以下程序#includemain{ FILE *fp;int a[10]={1,2,3,0,0},i;fp=fopen(d2.dat,wb);fwrite(a,sizeof(int),5,fp);fwrite(a,sizeof(int),5,fp);fclose(fp);fp=fopen(d2.dat,rb);fread(a.sizeof(int),10,fp);fclose(fp);for(i=0;i10;i++) printft(%d,a[i]);}程序的运行结果是( )。A.1,2,3,0,0,0,0,0,0,0,B.1,2,3,1,2,3,0,0,0,0,C.123,0,0,0,0,123,0,0,0,0,D.1,2,3,0,0,1,2,3,0,0,

有以下程序

#include

main

{ FILE *fp;

int a[10]={1,2,3,0,0},i;

fp=fopen("d2.dat,"wb");

fwrite(a,sizeof(int),5,fp);

fwrite(a,sizeof(int),5,fp);

fclose(fp);

fp=fopen("d2.dat","rb");

fread(a.sizeof(int),10,fp);

fclose(fp);

for(i=0;i<10;i++) printft("%d",a[i]);

}

程序的运行结果是( )。

A.1,2,3,0,0,0,0,0,0,0,

B.1,2,3,1,2,3,0,0,0,0,

C.123,0,0,0,0,123,0,0,0,0,

D.1,2,3,0,0,1,2,3,0,0,
