JavaScript Programming Assignment

PLEASE NOTE:  You must create and call a main function, and if instructed include additional functions called by the main. Make sure to use ES6 style of keywords => instead of the older function and for local scope variables use the keyword let and not a keyword var. Make sure to follow the requirements and recheck before submitting.

PROJECT GOAL:

Assume that hot dogs come in packages of 10, and hot dog buns come in packages of 8. Write a program called cookout.js, that calculates the number of packages of hot dogs and the number of packages of hot dog buns needed for a cookout, with the minimum amount of leftovers.

The program will prompt for the number of people attending the cookout and as how many hot dogs each guest will eat. The program should display the following details.

The minimum number of packages of hot dogs required.

The minimum number of packages of hot dog buns required.

The number of hot dogs that will be left over.

The number of hot dog buns that will be left over.

Answer 1

/* Javascript program that calculates the number of packages of hot dogs
and the number of packages of hot dog buns needed for a cookout, with the minimum amount of leftovers*/

let readline = require('readline-sync'); // module for taking input

var main = () =>{
  
   //input of the number of people attending the cookout
   let num_people = parseInt(readline.question("Enter number of people attending the cookout? "));
   // input of number of hot dogs each guest will eat
   let num_hotdogs = parseInt(readline.question("Enter the number of hotdogs each guest will eat? "));
  
   // variables to set the number of hotdogs per package and hotdog buns per package
   let hotdogs_per_package = 10;
   let hotdog_buns_per_package = 8;
  
   let hotdog_packages,hotdog_buns_packages;
  
   // calculate the total hotdogs
   let total_hotdogs = num_people * num_hotdogs;
  
   // calculate hotdogs packages
   if(total_hotdogs%hotdogs_per_package == 0)
       hotdog_packages = parseInt(total_hotdogs/hotdogs_per_package);
   else
       hotdog_packages = parseInt(total_hotdogs/hotdogs_per_package)+1;
  
   // calculate hotdog buns packages
   if(total_hotdogs%hotdog_buns_per_package == 0)
       hotdog_buns_packages = parseInt(total_hotdogs/hotdog_buns_per_package);
   else
       hotdog_buns_packages = parseInt(total_hotdogs/hotdog_buns_per_package)+1;

   // calculate hotdogs leftovers
   let hotdog_leftover = (hotdog_packages*hotdogs_per_package) - total_hotdogs;
   // calculate hotdog buns leftovers
   let hotdog_buns_leftover = (hotdog_buns_packages*hotdog_buns_per_package)-total_hotdogs;
  
   // output
   console.log("The minimum number of packages of hot dogs required : "+hotdog_packages);
   console.log("The minimum number of packages of hot dog buns required : "+hotdog_buns_packages);
   console.log("The number of hot dogs that will be left over : "+hotdog_leftover);
   console.log("The number of hot dog buns that will be left over : "+hotdog_buns_leftover);
}

// call the main function
main()

//end of program

Output:
