// Javascript Correction

// Created by faizaanceg on 05/11/15.

// Reviewed by:

// - No one yet.

// Part One:

// FIXME: Declare variables

// Declare two variables: an integer named "age", and a string named "name" with corresponding values (your name and age)

var age = 20

var name = "Faizaan"

// FIXME: Print

// Print the following sentence in the console "You are NAME and you are AGE years old !". Don't forget to add a newline at the end

console.log("You are", name, "and you are", age, "years old!")

// FIXME: Concatenation

// Create a new string variable called "hello" which value is "Hello ". Add "name" at the end of "hello" (Concatenation) then print it

var hello = 'Hello '

hello = hello + name

console.log (hello)

// FIXME: Array

// create a new string array called "shoppingList", with three elements of your choice. Create an int variable containing the number of

// elements in "shoppingList" (using a function of the array/using the array)

var shoppingList = ["Sugar", "Honey", "Donuts"]

var noOfElts = shoppingList.length

console.log (noOfElts)

// FIXME: For-loop - Integer

// Create a simple for-loop for an integer "i" going from 1 to 10 that prints the value of "i"

for(var i = 0; i < 10 ; i++) console.log(i)

// FIXME: For-loop - shoppingList

// Create a for loop that iterate through "shoppingList" and prints each element.

for(var i = 0; i < noOfElts ; i++) console.log(shoppingList[i])

// FIXME: Foreach-loop

// Do the same with a foreach-loop.

shoppingList.forEach(function(value) { console.log(value) })

// FIXME: If-statement

// Modify the first for-loop (with i from 1 to 10) such that it console.logs "(value of i) is even" when "i" is divisible

// by 2 (You may want to learn more about "modulo" (%)). Else, print "(value of i) is odd".

for(var i = 0 ; i < 10; i++)

if (i % 2)

console.log (i + " is odd")

else

console.log (i + " is even")

// FIXME: Sum Up

// Create a string variable called "element" with the value of your choice. Then create a for-loop that checks if "shoppingList" contains

// "element". If yes, print "You have to buy (value of element) !", and stop the loop (search how to stop a loop).

// If not, print "Nope, you don't need (value of "element")".

console.log ("Nope, you don't need", element)

// Part Two:

// FIXME: Functions - Ascii

// Create a function that returns nothing and which doesn't takes any parameter. It should just be named "TriForce"

// and print the TriForce symbol (one triangle over two other ones, can be found on internet) with "TRIFORCE"

// Don't forget to call the function !

// FIXME: Functions - One parameter

// Create a function that takes a string as parameter and returns "Hello (value of string) !"

function Hello(str) { return "Hello " + str + "!" }

console.log(Hello("Faizaan"))

// FIXME: Functions - Multiple parameters

// Create a function that takes two integers as parameters and returns the addition of these two.

// You can do the same with multiplication, subtraction and division.

function Addition(a, b) { return a+b }

function Subtraction(a, b) { return a-b }

// Create a two dimensional int array of 3 columns and 3 rows. Use 2 for-loops to add a random number

// between 1 and 9 in each of the 9 rooms.

// You may use one of the two previously created function.

// Then print them such that they appear like this (with [x1,x9] being the 9 random integers):

// {x1,x2,x3,}

// {x4,x5,x6,}

// {x7,x8,x9,}

// FIXME: Switch

// Create a Switch that takes an integer "a" and return a sentence regarding the value of a

// (Create 3 statements for 3 specific values and a functionault one)

// FIXME: logic Gates

// Create 7 functions for each logic gates (and, or, not, nand, nor, xnor, xor).

// Each function takes two booleans (or 0 and 1) as parameters and returns the result of the logic gate.

// (or You can do it with a switch and only one function)

// Logic gates are already well represented in JS. So, here they are represented in NAND logic.
