I beg you, please, help me.... :(

The problem : http://codeforces.com/problemset/problem/4/A

my solution :

#include <iostream>

using namespace std;

int main(void)
{
	int w=(1<=w<=100);

	cin >> w;

	if (w%2==0)
		cout << "YES";
	else
		cout << "NO";

	return 0;
}

but when everyitme i submit, and the site test my code, then the site always say "Wrong answer on test 5". Test 5 maybe means line 5 (?). Is there anything wrong with my solution ? Thanks.

This line is not valid c++ syntax (and doesn't make any sense)
int w=(1<=w<=100);

Do you want w to be a random number between 1 and 100? If so the code is:
int w = rand()%100;

EDIT: I see in the problem-text that it says 1<=w<=100. That just means that the input your code will be getting will be between 1 and 100 inclusive.

In line 7, you only need int w;
The problem described w as an integer between 1 and 100 for your own personal information; it doesn't affect the coding at all, and you don't need to initialize w here, since the cin in the next line does so. Other than that your code looks fine.

Also, your code doesn't correctly answer the problem. In addition to checking w%2==0, you also need to check that the two parts are even :)

Read the problem carefully.
Test the limits. By instance, ¿which should be the output for `w=2'?
