Answer:
To check if the year comes under each 100th year, lets check if the remainder when dividing with 100 is 0 or not.
Similarly check for 400th year and multiple 0f 4. The following C program describes the function.
#include<stdio.h>
#include<stdbool.h>
bool is_leap_year(int year);
void main()
{
 int y;
 bool b;
  
 printf("Enter the year in yyyy format: e.g. 1999 \n");
 scanf("%d", &y);     // taking the input year in yyyy format.
  
 b= is_leap_year(y);  //calling the function and returning the output to b
 if(b==true)
 {
  printf("Thae given year is a leap year \n");
 }
 else
 {
  printf("The given year is not a leap year \n");
 }
}
bool is_leap_year(int year)
{
 if(year%100==0)   //every 100th year
 {
  if(year%400==0)   //every 400th year
  {
  	return true;
  }
  else
  {
  	return false;
  }
 }
 if(year%4==0)  //is a multiple of 4
 {
  return true;
 }
 else
 {
  return false;
 }
}

Answer:
offline backup solution
Explanation:
In such a scenario, the best option would be an offline backup solution. This is basically a local and offline server that holds all of the flight record data that the cloud platform has. This offline backup server would be updated frequently so that the data is always up to date. These servers would be owned by the aviation company and would be a secondary solution for the company in case that the cloud platform fails or the company cannot connect to the cloud service for whatever reason. Being offline allows the company to access the database regardless of internet connectivity.
