Accepting input from console in Node.Js

By Sidharth Patnaik -
In this post, we will demonstrate how to accept input and perform operation in node.js from a console. Node.js is an open-source, cross-platform runtime environment for developing server-side web applications. Node.js applications are written in JavaScript and can be run within the Node.js runtime on OS X, Microsoft Windows, Linux, FreeBSD, NonStop, IBM AIX, IBM System z and IBM i.

Screenshot:


The Code 
var readline = require('readline');

var rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout
});

rl.question("What is your name ? ", function(answer) {
  // TODO: Log the answer in a database
  console.log("Hello "+answer+" how are u ?");
  rl.close();
});
Got any doubts, just go ahead and comment them ! :)

This  is a Dynamic program for the implementation of the NON RESTORING Division Algorithm in C Language. Non Restoring Division uses Left Shift Operations, Twos' Compliment and Binary Addition. Screenshots[Demo] The Code #include<stdio.h> #include<malloc.h> int *a,*q,*m,*mc,*c,n,d; int powr(int x,int y) { int s=1,i; for(i=0;i<y;i++) s=s*x; return s; } void print(int arr[],int n) { int i; for(i=0;i<n;i++) printf("%d ",arr[i]); } void bin(int n, int arr[]){ int r, i = 0; do{ r = n % 2; n /= 2; arr[i] = r; i++; }while(n > 0); } void set(int array[], int x){ int i,tmp[20]={0}; for(i = x -1; i >=0; i--) tmp[x-1-i]=array[i]; for(i=0;i<x;i++) array[i]=tmp[i]; } int len(int x) { int i=0; while(powr(2,i)<=x) i++; return ++i; } void addBinary(int a1[], int a2[]) { int bi[2]={0},ca[20]={0}; int t=len(n),tmp=0; int *su=(int*)malloc(sizeof(int)*len(n)); while(t...

This is an implementation of the Bit Stuffing popularly used in data communication, also known as one of the concepts of Framing data bits. To know more please  click here. Sample Output: This is a sample output with data binary data entered as 11001111110. Program Code: import java.util.*; public class BitStuffing { public static void main(String[] args) { System.out.print("Enter the Binary message: "); Scanner sn=new Scanner(System.in); String data = sn.nextLine(); String res = new String(); String out=new String(); int counter = 0; for(int i=0;i<data.length();i++) { if (data.charAt(i)!='1' && data.charAt(i)!='0') { System.out.println("Enter only Binary values!!!"); return; } ...

This program will help you in creating an simple Employee Management System using java language. In this program a class emp is used which has name, id and salary as data members. inside it there are two methods namely get() and disp() which work as getting user input and displaying the output. Scanner class is used as well. This program is an implementation of array of objects. Sample Output : The Code here: import java.util.*; class emp { public String name; public int id,sal; public void get() { Scanner s=new Scanner(System.in); System.out.print("Enter The Name: "); name=s.next(); System.out.print("Enter The id: "); id=s.nextInt(); System.out.print("Enter The sal: "); sal=s.nextInt(); s.close(); } public void disp() { System.out.println("The Name of the employee is "+name+" having id: "+id+"and a salary worth to: "+sal); } } class MainClass extends emp { publ...
