Question

C++

Given 2 int arrays that are related, sort them correspondingly.

EXAMPLE:

int arr1[] = {84, 4, 30, 66, 15};

int arr2[] = {7, 5, 2, 9, 10};

SORTED ANSWER:

4 - 5

15 - 10

30 - 2

66 - 9

84 - 7

Answer 1

Below is your code: -

#include<iostream>
using namespace std;

int main() {
   //declaring arrays
   int arr1[] = {84, 4, 30, 66, 15};
   int arr2[] = {7, 5, 2, 9, 10};
   //getting size of first array
   int n = sizeof(arr1)/sizeof(arr1[0]);
   //code to sort the arrays
   //traverse first array
   for(int i=0; i<n; i++)
   {      
       //compare it with subsequent member of first array
       for(int j=i+1; j<n; j++)
       {
           //If array element is unsorted
           //sort first array and swap elemnt of second array also
           if(arr1[i] > arr1[j])
           {
               int temp1 =arr1[i];
               int temp2 =arr2[i];
               arr1[i]=arr1[j];
               arr2[i]=arr2[j];
               arr1[j]=temp1;
               arr2[j]=temp2;
           }
       }
   }
  
   cout<<"SORTED ANSWER: "<<endl;
   //printing the array
   for(int i = 0; i < n; i ++) {
       cout<<arr1[i]<<" - "<<arr2[i]<<endl;
   }
  
   return 0;
}

Output

SORTED ANSWER:
4 - 5
15 - 10
30 - 2
66 - 9
84 - 7
