Write a program named ChatAWhile that stores the area codes and rates in parallel arrays and allows a user to enter an area code and the length of time for a call in minutes, and then display the total cost of the call.

import java.util.Scanner; public class Main {    public static void main(String[] args)    {        int areaCode[] = {121, 122, 123, 124, 125};        double rates [] = {0.2, 0.3, 0.35, 0.15, 0.25};        Scanner input = new Scanner(System.in);        System.out.print("Enter area code: ");        int a = input.nextInt();        System.out.print("Enter calling time: ");        int time = input.nextInt();        double cost = 0;        for(int i=0; i < areaCode.length; i++){            if(areaCode[i] == a){                cost = rates[i] * time;            }        }        System.out.println("Total cost of the call: $" + cost);    } }

Explanation:

The solution code is written in Java.

Firstly create two parallel arrays for area code and calling rate (Line 7-8). Presume the rate is based on call per minute.

Next, user Scanner object to prompt user to input area code and calling time (Line 10 - 14).

Create a for loop to identify the index where the input area code can be found in the array  and then calculate the cost by using the same index i to get the corresponding rate (Line 17 - 20).

Print the cost to console (Line 22).  

Yes, by adjusting the boot order.

Hey i m confused bw c and d. but i think u can go for c
