} Mihran you must set value of S equal to zero,before "for(...) S=S+i;".Good luck!
Edited by author 07.05.2009 17:39 why the compiler does not accept the job site?
that do not correctly?
#include <iostream>
#include <math.h>
using namespace std;
int main()
{
int N;
int H=0;
int S=0;
int i;
cin>>N;
if(((N<10000)&&(N>1))||((N>-10000)&&(N<-1)))
{
H=abs(N);
for( i=2;i<=H;i++) S=S+i;
if(N<0) cout<<endl<<S*(-1);
else cout<<endl<<S;}
else cout<<"error";
return 0;
