You are given two int variables j and k, an int array zipcodeList that has been declared and initialized, an int variable nZips that contains the number of elements in zipcodeList, and a bool variable duplicates. Write some code that assigns true to duplicates if any two elements in the array have the same value, and that assigns false to duplicates otherwise. Jse only j, k, zipcodeList, nZips, and duplicates.

This question is in javaYou are walking along a hiking trail. On this hiking trail, there is elevation marker at every kilometer. The elevation information is represented in an array of integers. For example, if the elevation array is [100, 50, 20, 30, 50, 40], that means at kilometer 0, the elevation is 100 meters; at kilometer 1, the elevation is 50 meters; at kilometer 2, the elevation is 20 meters; at kilometer 3, the elevation is 30 meters; at kilometer 4, the elevation is 50 meters; at kilometer 5, the elevation is 40 meters. a) Write a method called dangerousDescent that determines whether there is a downhill section in the hiking trail with a slope of more than -0.05. The slope is calculated by the rise in elevation over the run in distance. For example, the last kilometer section has a gradient of -0.01 because the rise in elevation is 40 - 50 = -10 meters. The distance covered in 1000 meters. -10 / 1000 = 0.01. Your method should return true if there exists a dangerous…

Write a program that uses two classes. The first class is called “dAta” and holds x and y coordinates of a point in 2-d space called p1. The second class is called “cOmpute” and holds an array of two pointers to the “dAta” class. The “cOmpute” class has a function, lOad(float x, float y, int n), which loads x and y coordinate data into the array at index n. It also has a function, sLope(), which computes the slope of the line connecting the two array data coordiantes. It also has a function, pRint(), which prints the slope result to the screen. Implement a divide by zero exception using throw in the sLope() nd/or pRint() function as appropriate. The exception should, when caught, print “Slope calculation error…” to the screen and exit the function. The program should load the array with some example points and print the slope to the screen using the class functions.

A method named getUserStringsAndPopulate Array(). This method should keep prompting the user to enter as many strings as the user wants. The user should be able to stop entering strings by entering EXIT. This method should take the strings entered by the user and populate a one-dimensional array of strings with the user input. The string EXIT should NOT be added to the array because it is a special flag that will tell the method to stop prompting the user to enter more strings. This method should return the one-dimensional array of strings populated with user input and should not accept any arguments. 2.b) A method named searchArray() that would accept a one-dimensional array of strings and search the array for the string Winter. The search logic should NOT be case sensitive. If a match is found, this method should print the string in the array followed by a message like "  --- Found a match!". Otherwise, the method should not print anything. This method should NOT return anything.…
