有以下程序
#include
main( )
{ FILE *fp; int i, a[6] = {1,2,3,4,5,6};
fp=fopen("d2.dat", "w+");
for(i = 0; i < 6; i++) fprintf(fp, "%d\n", a[i]);
rewind(fp);
for(i = 0; i < 6; i++) fscanf(fp, "%d\n", &a[5 - i]);
fclose(fp);
for(i = 0; i < 6; i++) printf("%d,", a[i]);
}
程序运行后的输出结果是
A．4,5,6,1,2,3,
B．1,2,3,3,2,1,
C．1,2,3,4,5,6,
D．6,5,4,3,2,1,
