Problem 4. monthlybilling.js(.split is introduced)

 /*

Given the unit price, number of units per day and
the number of days in a given month,
compute the monthly bill.
Input:
one line containing 3 integers seperated by spaces.
First integer denotes the unit price.
Second integet denotes the no. of units per day.
Third integer denotes the no. of days in a month.

Output:
one integer denoting the monthly bill.
Example:
Input:-
5.2 2 30
20 2 30

Expected output:
312
600

Algorithm:
1. Read the price per unit
2. Read the no. of units per day
3. Read the no. of days in a month
4. Apply or calculate the final bill
5. Display final amount

Problem 16. chocolatebills.js

  /*Question Chocolate bill Bablu went to a shop to buy some chocolates and ice creams. Help him to calculate the bill. Input 4 lines containing one integer each First line denotes the cost of 1 chocolate. Second line denotes the number of chocolate bought by Bablu. Third line denotes the cost of 1 ice cream. Fourth line denotes the number of ice creams bought by Bablu. Output One line containing one integer, denoting the total money to be paid by Bablu. Example Input: 5 3 15 2 Output: 45 Explanation: First line contains 5, which means the cost of one chocolate is 5 rupees. Second line contains 3, which means Bablu bought 3 chocolates. Third line contains 15, which means the cost of one ice cream is 15 rupees. Fourth line contains 2, which means Bablu bought 2 ice creams. So, the total bill is 45 rupees. */ let fs = require ( "fs" ); let data = fs . readFileSync ( 0 , 'utf-8' ); let idx = 0 ; data = data. split ( ' \n ' ); function readLine () { i...
