Bug is in the below lines of code

temp=arr[i];
arr[i]=arr[arr[i]+1];
arr[arr[i]+1]=temp;

Why there is bug :

suppose arr[0] is 0 and arr[1]=1
temp=arr[0]// now temp is 0
arr[i]=arr[arr[i]+1];// now arr[0] is 1 
arr[arr[i]+1]=temp;//arr[2] is now 0 and about arr[1] we are not setting it and arr[2] value is also lost

What is the solution :

Store the values before swapping :

int temp1=arr2[i];
int temp2=arr2[arr2[i]+1];
//swapping
arr2[arr2[i]+1]=temp1;
arr2[i]=temp2;//it should be below, don't assign arr2[i] earlier

Source with logical bug fixed :

#include <iostream>

using namespace std;

//swap
void swap(int &a,int &b){
    //cout<<"swap "<<a<<" "<<b<<endl;
    int temp=b;
    b=a;
    a=temp;
}

int main(){
    int n;
    cin>>n;
    //arr is swapped using swapped method
    int arr[n],i,temp;
    //arr2 is swapped using temp variable
    int arr2[n];
    for(i=0;i<n;i++) {
        cin>>arr[i];
        arr2[i]=arr[i];
    }
    for(i=0;i<n;i++) {
        swap(arr[i],arr[arr[i]+1]);
        //cout<<"swap2 "<<arr2[i]<<" "<<arr2[arr2[i]+1]<<endl;
        //swap(arr2[i],arr2[arr2[i]+1]);
        //store both the varibles before giving value
        int temp1=arr2[i];
        int temp2=arr2[arr2[i]+1];
        //arr2[i]=arr2[arr2[i]+1];
        //arr2[arr2[i]+1]=temp;
        //swapping
        arr2[arr2[i]+1]=temp1;
        arr2[i]=temp2;
        /*
           cout<<"after swapping arr"<<endl;
           for(int j=0;j<n;j++) {
           cout<<arr[j]<<" ";
           }
           cout<<endl;
           cout<<"after swapping arr2"<<endl;
           for(int j=0;j<n;j++) {
           cout<<arr2[j]<<" ";
           }
           cout<<endl;
           */
    }
    for(i=0;i<n;i++) {
        cout<<arr[i]<<" ";
    }
    cout<<endl;
    for(i=0;i<n;i++) {
        cout<<arr2[i]<<" ";
    }
}

Input :

$ g++ array.cpp && ./a.out
4
0 1 2 2
1 0 2 2 
1 0 2 2 

Answer 2

If your goal is to swap every element with the element next to it as you move through the array from 0 to n then all you need is: swap(arr[i], arr[i+1]); You will have to be sure to stop before i+1 is greater than the number of indexes in your array.

if(i+1 >= n) break;
