Add sidekiq to your Gemfile: Add this to your Gemfile gem 'sidekiq' Run bundle install bundle install Create worker rails g sidekiq:worker Test #will create app/workers/test_worker.rb class TestWorker   include Sidekiq::Worker   def perform(id, name)     # do something   end end Call worker without any time boundation TestWorker.perform_async(5, 'rahul') //use this anywhere from your rails app(controller, model, helpers..) Call worker within particular time period TestWorker.perform_in(5.minutes, 5, 'rahul')  //use this anywhere from your rails app(controller, model, helpers..) Call worker after specific time interval once only TestWorker.perform_at(5.minutes.from_now, 5, 'rahul')  //use this anywhere from your rails app(controller, model, helpers..) Start sidekiq on development bundle exec sidekiq Start sidekiq on production bundle exec sidekiq -d //run this first if you get some error then use second one bundle exec si

A   structure   enables us to treat a number of different variable stored at different places in memory. A  union   enables us to treat the same space in memory as a number of different variable.

#include<stdio.h> #include<conio.h> void printFibonacci(int n){ static int n1=0,n2=1,n3; if(n>0){ n3 = n1 + n2; n1 = n2; n2 = n3; printf("%d ",n3); printFibonacci(n-1); } } void main(){ int n; clrscr(); printf("Enter the number of elements: "); scanf("%d",&n); printf("Fibonacci Series: "); printf("%d %d ",0,1); printFibonacci(n-2); //n-2 because 2 numbers are already printed getch(); } Enter the number of elements : 15 0 1 1 2 3 5 8 13 21 34 55 89 144 233 377

Bit fields are not portable . Because  bit fields cannot span machine words , and because the number of bits in a machine word is different on different machines, a particular program using bit fields might not even compile on a particular machine. Assuming that your program does compile, the order in which bits are assigned to bit fields is not defined. Therefore, different compilers, or even different versions of the same compiler, could produce code that would not work properly on data generated by compiled older code. Stay away from using bit fields, except in cases in which the machine can directly address bits in memory and the compiler can generate code to take advantage of it and the increase in speed to be gained would be essential to the operation of the program.

Bit fields are used in Data Structure and it is partial size member variables inside a structure. When we use number programming that time we use Bit fields. Example- Decimal to Binary Conversion In the Bit fields left most bit is called sign bit.
