i think if you try to init x and y as 10e-6,you will get AC.
GOOD LUCK.

yes,i can use scanf(). but i don't know much about the function in C. In UVA, the most input is terminated by End Of File. when i use stream, cin will throw an exception when it read EOF, i use
[cpp] while (cin >> a)[/cpp] to find the End Of File.
If i use scanf(), how should i write
[c]while ...

Oh,my god.
yes,you are right, i use "Choice",then ACC.
Thank you.

I use TC and VC++. They have the same problem.
My OS is Windows.
can i include <iostream>?
i always use iostream.h.
Thank you.

I am writing a program about clock these days.
but there are a little problem about input, then i have writen a test program.And i have found a strange thing.
This is my code:
[cpp]
#include <iostream.h>

void main()
{
int a;
while (cin >> a)
cout << a << endl;
}
[/cpp]


input:
15
00
01
02
05 ...

I have tested my code for many inputs,and i have been careful to the output format. But it always gets WA. :( Please help me,Thank you. :D :D :D
[cpp]
#include <iostream.h>
#include <stdio.h>

void main()
{
long int step,mod,i,seed,j;
long int flag;
while (cin >> step >> mod)
{
for (i = 0;i ...

why my answer always gets PE?
[cpp]
#include <iostream.h>
#include <stdio.h>

int main()
{
long n,i,b;
while (cin >> n)
{
b = 1;
for (i = 1;i <= n;i++)
{
b *= i;
while (!(b % 10))
b /= 10;
b %= 100000;
}
while (!(b % 10))
b /= 10;
b %= 10;
printf ("%5ld -> %ld\n",n,b);
}
return 0 ...

i have checked my code and got AC
thanx

oh,i see.
and i have changed a new way to slove this problem and got accepted.
Thanx.

2 is the right answer?
why?
i think 3 is the right answer. And my code get the answer 3.

Please help me!
why WA?
[cpp]
#include <iostream.h>
#include <stdio.h>

int max = 104;
int k;
int sum[105];

void main()
{
char c;
int i,j,k1,x;
int sum1[105];
k = max;
while (1)
{
for (i = 0;(c = getchar()) != '\n';i++)
sum1 = c - 48;
if (!sum1[0]) break;
k1 = i - 1;
j = max;
x = 0 ...

Why my code is WA?
Please help me!
