请帮我分析下 这个程序的运行结果#include"stdio.h"
#define N 10
main()
{
int a[10]={2,4,6,8,10,12,14,16,18,20},i;
FILE *fp;
fp=fopen("tt.dat","w");
for(i=0;i<10;i++)
fprintf(fp,"%d\t",a[i]);
fclose(fp);
fp=fopen("tt.dat","r");i=0;
while(!feof(fp)) {fscanf(fp,"%d\t",a[i]);i++;}
for(i=0;i<10;i++)
printf("%d\t",a[i]);
}
