Trying to make this code show all variants of writing a number as sum of consecutive numbers,but most of the times shows nothing

#include <iostream> using namespace std; int main() { int n,i,j,s,k; cin>>n; for(i=1;i<=n/2;i++) { j=i; s=0; while(s<n) { s+=j; j++; } if (s==n) for (k=i;k<=j-1;k++) { cout <<k<<" "; } cout <<endl; } return 0; }

Well 17 cannot be expressed as sum of consecutive numbers. Entered 18,21,33 and got correct output.

17 cannot be expressed as sum of consecutive numbers. Sorry for that. didn't paid attention. scroll down in output screen. The last cout<<endl; repeats so many times that it takes the output outside the visible region.
