For this problem,when I used G++,I got AC,but when I used GCC,I got WA so many times.
Why?
#include<stdio.h>
#include<math.h>
int main()
{
     double b[3000000];
     int n=0;
     double temp;
     while(scanf("%lf",&temp)!=EOF)
          b[n++]=sqrt(temp);
     for(int i=n-1;i>=0;i--)
          printf("%.4lf\n",b[i]);
     return 0;
}
