int main(){
    
    int n ;
    cout<<"enter size if array : ";
    cin>>n;
    int arr[n];
    cout<<"Enter "<<n<<" Array : ";
    for(int i=0;i<n;i++){
        cin>>arr[i];
    }
    cout<<"The array you entered is :";
    for(int i=0;i<n;i++){
        cout<<arr[i]<<" ";
    }
    cout<<endl;
    int sum=0;
    for(int i=0;i<n;i++){
    sum+=arr[i];
    }
    cout<<"the addition of all elements in the array is :" <<sum;
    
    return 0;
    
}

Que. Take n no. Of elements and arrange them in Ascending & Descending Order    Code:- #include<iostream> //or #include<bits/stdc++.h> //^ this one is awesome for doing all kind of stuff in c++ and also you dont have to include any other header file ,if you enter this one  using namespace std; int main (){     int n ;     cout<<"write size of array:";     cin>>n;     int arr[n];     for(int i =0, j=1;i<n,j<n+1;i++,j++){         cout<<"enter "<<j<<"th location value: ";         cin>>arr[i];         cout<<" ";     }              //program for arranging in ascending order using for loop      for(int j=0;j<n;j++){         for(int i=0;i<n;i++){             if(arr[i]>arr[i+1]){   ...
