I can't know why it gives me CE.

Code: Select all

//uva 10986 sending e-mails

#if 1
typedef long long xint;
#define format "%lld\n"
typedef __int64 xint;
#define format "%I64d\n"

#include <stdio.h>
#include <queue>
#include <vector>
#include <algorithm>
#include <functional>

using namespace std;

vector< pair<int, int> > gr[20001];
xint c[20001]; bool d[20001];

Did you get an email explaining the compiler errors?

In gcc 2.95 file iostream.h contains this definitions:

Code: Select all

    ostream& form(const char *format ...);
    ostream& vform(const char *format, _IO_va_list args);

    istream& scan(const char *format ...);
    istream& vscan(const char *format, _IO_va_list args);
You defined format to be "%lld\n", so they don't make any sense anymore.

Move your defines after all the includes and you will be fine. This is a general rule: don't define anything before includes unless you want to change how libraries behave.

Krzysztof Duleba, Thanks very much.
I will keep in mind that a trivial but very important rule!
