The following code is failing the test case 3, I have used linked-list to store the data in as a stack. Below is the code for reference, can you tell me where I am going wrong. Thank you.

#include<stdio.h>
#include<stdlib.h>
#include<stdbool.h>
#include<math.h>
#include<assert.h>

typedef unsigned long long _ull;
typedef unsigned int _uint;

typedef struct _link_list {
    _ull _number;
    struct _link_list*_next;
} _list;

void _makenode(_list**,_ull);
void _insertnode(_list**,_list*);

int main(int argc,const char*argv[]) {
    _ull _val;
    _list *_head,*_temp;
    _head = _temp = NULL;
    while(true) {
        fscanf(stdin,"%lld",&_val);
        assert(_val>=0);
        if(feof(stdin)) break;
        _makenode(&_head,_val);
    }
    while(_head) {
        _temp = _head;
        fprintf(stdout,"%0.4lf\n",sqrt(_head->_number));
        _head = (_head->_next);
        free(_temp);
    }
    return 0;
}

void _makenode(_list**_ptr,_ull _data) {
    _list*_node = malloc(sizeof(_list));
    (_node->_number) = _data;
    (_node->_next) = NULL;
    _insertnode(_ptr,_node);
}

void _insertnode(_list**_ptr,_list*_node) {
    if(!(*_ptr)) (*_ptr) = _node;
    else {
        (_node->_next) = (*_ptr);
        (*_ptr) = _node;
    }
}

I've created file with tests, it seems all checks passes locally, but not in Judge
here is my code:
#include <stdio.h>
#include <stdlib.h>
#include <math.h>

typedef struct list_node{
    long int number;
    struct list_node * previous;
} list_node_t;

list_node_t * create_root(long int number);
list_node_t * create_list(long int number, list_node_t * previous);

int main() {
    long int a;
    list_node_t * current = NULL;
    while (scanf("%ld", &a) != EOF) {
        if (current == NULL) {
            current = create_root(a);
        } else {
            current = create_list(a, current);
        }
    }

    while (current != NULL) {
        printf("%.4Lf\n\r", sqrtl(current->number));
        current = current->previous;
    }

    return 0;
}

list_node_t * create_root(long int number)
{
    list_node_t *lt = malloc(sizeof(list_node_t));

    lt->number = number;
    lt->previous = NULL;

    return lt;
}

list_node_t * create_list(long int number, list_node_t * previous)
{
    list_node_t *lt = create_root(number);

    lt->previous = previous;

    return lt;
}

#include <iostream>;
#include <vector>;
#include <string>;
#include <sstream>;
#include <iomanip>
using namespace std;
int main()
{
    int temp;
    vector <double> answers;

    string s;
    getline(cin, s);

    istringstream iss(s);
    while (iss >> temp)
    {
        double a = sqrt(temp);
        answers.push_back(a);
    }

    for (int i = answers.size(); i > 0; i--)
    {
        cout << fixed << setprecision(4) << answers[i-1];
        cout << endl;
    }

    system("pause");

    return 0;
}

This is my code
-----------------------------------------
var
  j,i: longint;
  a: array[1..100000000] of real;
begin
  i:=1;
  while not EOF do
  begin
    read(a[i]);
    i:=i+1;
  end;
  for j:=i-1 downto 1 do
    writeln(sqrt(a[j]):0:4);
end.
-----------------------------------------

Why is it wrong? can anyone please explain? thanks a lot

скорее всего ошибка с функцией Eof() ибо впервые ей пользуюсь и смутно представлю принцип работы. Если её нельзя использовать, то как найти конец вводимого файла?

var s,sk:string;
var i,fl,j,code:integer;
var n:real;
var a:array [1 ..256] of real;
var f:array [1 ..256] of integer;
begin
while (Eof()<>True ) do
 begin
 readln(s);
 for i:=1 to length(s) do
 begin
 if (s[i]<>' ') and (fl=0) then begin
                               fl:=1;
                               sk:=sk+s[i];
                               end
else  if (s[i]<>' ') and (fl=1) then sk:=sk+s[i];

 if (((s[i]=' ') and (fl=1)))or ((i=length(s))and(fl=1)) then begin
                                 fl:=0;
                                 val(sk,n,code);
                                 for j:=1 to 256 do
                                 if f[j]<>1 then begin
                                                 a[j]:=sqrt(n);
                                                 f[j]:=1;
                                                 sk:='';
                                                 n:=0;
                                                 break;
                                                 end;

                                 end;
 end;end;
for i:=1 to 256 do
if (f[i]=1) then writeln(a[i]:0:4);

На каких значениях становить ввод?

L = []
string = input()

while string:
    [L.append(int(num)**0.5) for num in string.rstrip().split(' ') if num != '']
    string = input()

for i in L[::-1]:
    print('%.4f'%i)
