Hit and Slopes Program: A Write a program that can be used by a ski resort to keep track if local snow conditions for one week. It should have two seven-element arrays to store the date and number of inches of snow (consider the parallel array concept discussed in the class). First, the program should ask the user to enter the name of the month. Then, it should have the user enter dates and corresponding snow fall. Once data is entered, store them in two arrays mentioned above. Then, the program should produce a report for the week with following information. a) Highest snow fall. b) Average snow fall.

Answer:

The java program is as follows.  

import java.lang.*;  

import java.util.Scanner;  

public class Main  

{  

//array declaration  

static int weekdays=7;  

static int[] snowfall_inch = new int[weekdays];  

static String[] snowfall_date = new String[weekdays];  

//variables to store average and maximum  

static double avg;  

static int max;  

public static void main(String[] args) {  

Scanner sc = new Scanner(System.in);  

System.out.print("Enter the month: ");  

String month = sc.next();  

for(int n=0; n<weekdays; n++)  

{  

System.out.print("\nEnter the date for day "+(n+1)+ ": ");  

snowfall_date[n] = sc.next();  

System.out.print("Enter the inches of snowfall for day "+(n+1) +": ");  

snowfall_inch[n] = sc.nextInt();  

avg = avg + snowfall_inch[n];  

}  

avg = avg/weekdays;  

System.out.printf("The average snowfall for the week is %.4f",avg);  

for(int n=0; n<weekdays-1; n++)  

{  

if(snowfall_inch[n] < snowfall_inch[n+1])  

max=snowfall_inch[n+1];  

}  

System.out.println("\nThe maximum snowfall for the week is "+max);  

}  

}  

OUTPUT  

Enter the date for day 2: 12-2-2019

Enter the inches of snowfall for day 2: 23  

Enter the date for day 3: 12-3-2019

Enter the inches of snowfall for day 3: 13  

Enter the date for day 4: 12-4-2019

Enter the inches of snowfall for day 4: 14  

Enter the date for day 5: 12-5-2019

Enter the inches of snowfall for day 5: 34  

Enter the date for day 6: 12-6-2019

Enter the inches of snowfall for day 6: 34  

Enter the date for day 7: 12-7-2019

Enter the inches of snowfall for day 7: 22

The average snowfall for the week is 21.7143  

The maximum snowfall for the week is 34  

Explanation:

1. Two arrays are declared to store dates and snowfall inches with string and integer datatypes respectively.  

2. Variables are declared to store maximum and average snowfall values with integer and double datatypes respectively.  

3. User input is taken for the month, and the dates and snowfall inch values for a week. The input is taken in for loop.  

4. Next, for loop is used to find the average and maximum snowfall of the week.  

5. These values are displayed to the user as shown in the output.
