    有以下程序: #include <stdio.h> main() { FILE*fp; int i,a[6] = {1,2,3,4,5,6},k; fp = fopen("data.dat", "w+b"); fwrite(&a[0],sizeof(int),1,fp); for(i=1; i<6; i++) { fseek(fp, 0L, 0); fread(&k, sizeof(int), 1, fp); fseek(fp, 0L, 0); a[i] +=k; fwrite(&a[i], sizeof(int), 1, fp); } rewind(fp); fread(&k, sizeof(int), 1, fp); fclose(fp); printf("%d\n",k); } 程序的运行结果是______。[/i][/i]
    A: 21
    B: 6
    C: 123456
