Endl is not working

#1

my code is printing the output in the same line in spite of using endl
as you switch to another question everything goes off.

#2

Hi Aakash

Please hard refresh your page (ctrl + shift + R) it should work fine then, and you can submit a code and later can view that submission.

#3

#include<bits/stdc++.h> using namespace std; int dp(int n) { int dp[n]; dp[0]=0; for(int i=1;i<=n;i++) { if(i<=2) { dp[i]=i; } else { dp[i]=dp[i-1]+(i-1)*dp[i-2]; } } return dp[n]; } int main() { int t; cin>>t; while(t>0) { int n; cin>>n; int ans=dp(n); cout<<ans<<endl; t–; } }

#4

what is wrong with the code?

Hi @aakashnagpal98

If you are returning return dp[n]; then initially you should make the array dp of size n+1, because indexing of array always starts from 0 and ends at n-1.

And It’s a request that from next time please copy your code at cb.lk/ide, save it and share that link in your doubt. It will be easier for us to debug your code then and will be able to resolve your doubt faster.

I hope this helps you :slight_smile:

#include<bits/stdc++.h> using namespace std; int dp(int n) { int dp[n+1]; dp[0]=0; for(int i=1;i<=n;i++) { if(i<=2) { dp[i]=i; } else { dp[i]=dp[i-1]+(i-1)*dp[i-2]; } } return dp[n]; } int main() { int t; cin>>t; while(t>0) { int n; cin>>n; int ans=dp(n); cout<<ans<<endl; t–; } }

@aakashnagpal98
Use long long int instead of int in your code.
