Questions for Reliance Jio Technical Interviews

Question 1: Write a C++ program to find a maximum scalar product of two vectors

include<bits/stdc++.h>
using namespace std;
int main(){

   int arr1[] = {1, 2, 6, 3, 7};
   int arr2[] = {10, 7, 45, 3, 7};

   int n = sizeof(arr1)/sizeof(arr1[0]);

   //Sort arr1 in ascending order
   for(int i=0; i<n; i++){
       for(int j=i+1; j<n; j++){ if(arr1[i]>arr1[j]){
               int temp = arr1[i];
               arr1[i] = arr1[j];
               arr1[j] = temp;
         }
      }
   }

   //Sort arr2 in ascending order
   for(int i=0; i<n; i++){
       for(int j=i+1; j<n; j++){ if(arr2[i]>arr2[j]){
                int temp = arr2[i];
                arr2[i] = arr2[j];
                arr2[j] = temp;
          }
       }
    }

    int product = 0;
    for(int i=0; i<n; i++)
        product += arr1[i]*arr2[i];

}

Question 8: Name some popular operating systems.

Answer:

Microsoft, Linux, OSX, and Windows are some popular OS. 

Questions 9: What exactly is a multicast delegate?

Answer:

Each delegate object represents a single method. A delegate object, on the other hand, can store pointers to and invoke many methods. These types of delegate objects are known as multicast delegates or combinable delegates.
