有以下程序：
#include＜stdio.h＞
main()
FILE*fp; int k, n, a[6]=1, 2, 3, 4, 5, 6;
fp=fopen("d2. dat", "w");
fprintf(fp, "%d% d% d\n", a[0], a[1], a[2]); fprintf(fp, "% d% d% d\n", a[3], a[4], a[5]);
fclose(fp);
fp=fopen("d2. dat", "r");
fscanf(fp, "% d%d", ＆k, ＆n); printf("%d% d\n", k, n);
close(fp);
程序运行后的输出结果是
A) 12
B) 14
C) 1234
