cout<<"Ascending order is \n"; for(int i=0;i<c;i++) //(3) array indexes starts from 0 so use, i=0 instead of 1 andd condition i<c; { cout<<arr[i]<<" "; } cout<<endl; sort(arr,arr+c,greater<int>()); //(4)here same use c instead of n cout<<"Descending order is \n"; for(int i=0;i<c;i++) //(5)same here use i=0 to c { cout<<arr[i]<<" "; } } edit: https://code.sololearn.com/cKASQ0bcX57b/?ref=app

you can remove n variable because unused. And better to use #include<iostream> #include<algorithm> In place of #include <bits/stdc++.h> You're welcome.. edit: https://code.sololearn.com/cKASQ0bcX57b/?ref=app

Look at this code for reference: This is best for dynamically storing and sorting array. plus it sorts floats and integral values https://code.sololearn.com/cM95l02G31pX/?ref=app
