int main()
{
    long long buffer;
    long result[131072];
    int count = 0;
    int i;
    while( scanf( "%lld",&buffer ) != EOF )
        result[count++]= buffer;

    for( i = count-1; i >= 0; i-- )
        printf("%.4f\n",sqrt(result[i]));
    return (0);
}


Please help solve the problem

sqrt()的参数只能是double。自己改把。不会的话再说，我QQ： 992913926

hi
choice double type for array
and select printf("\n%.4lf",a[i]);Instead, your code.
