CS-161 Assignment #7

General Submit this lab using the Moodle system by the beginning of lab on the due date.

 Use the Attach File tool to attach your .cpp file with your solution.

 Each code file should have the standard comment at the top (see Assignment 1).

 Read information into all programs in the specified order. Do not ask for extra input. If a program says something like “ask the user for their name and the number of hours they worked” you MUST read in the name first, then the number of hours and not prompt for any other input.

 Readability and maintainability of your code counts. Poor formatting, confusing variable names, unnecessarily complex code, etc… will all result in deductions to your score.

Climb Stats Filename : assign7.cpp

Elevation information about a hike is recorded like the table shown below indicating that the hike starts at 1200 feet, after 1 mile is at 3000 feet, etc… This hike is 8 miles and consists of 9 data points:

Mile 0 1 2 3 4 5 6 7 8

Elevation 1200 3000 3450 2800 2900 1550 1750 1110 1200

Write a program that declares in main: const int HIKE_LENGTH = 9; This will represent the number of data points in the hike (not the number of miles). Then declares an array of ints of size HIKE_LENGTH. (I should be able to change the number of elevation points your code is working with by changing that one const.) You should then read in HIKE_LENGTH elevations into the array (assume we always input the data in order: mile 0, then 1, then 2…). After doing so, print:

 The highest point in the first half of the hike, the highest point in the second half of the hike and the highest point overall in the hike. (If there are an odd number of elevation readings, count the middle point as being in the first half).

 The average elevation of the hike to two decimal places.

 The number peaks - mile markers higher than the markers before and after it. (The first and last markers will never be considered peaks).

 The number of difficult segments of the hike - ones with an elevation change over 1000 ft (going up or down)

 The total vertical feet covered in the hike. (Add up the change between each marker and the next. Note that both up and down count as elevation change here: going up 800 ft and then down 300 ft would be a total change of 1100 ft.)

Sample run:

Enter elevations: 1200 3000 3450 2800 2900 1550 1750 1110 1200 Highest points: First half: 3450 Second half: 1750 Overall: 3450 Average elevation: 2106.67 Peaks: 3 Difficult segments: 2 Elevation change: 5280

Make sure to read the required functions below.

CS-161 Assignment #7

You should write and use the following functions to help do your work. You can add others as you see fit.

a) void getData(int heights[], int size) Read elevation data into the array from the console. Hint… while testing you might want to not use this function and just hard code some numbers into main: int elevations[] = {1200, 3000, 3450, 2800, 2900, 1550, 1750, 1110, 1200}; Once you are done with the other functions or about to turn in the assignment, remove the hard coded array and call this function instead.

b) int getHighestPointBetween(const int heights[], int startMile, int endMile) Return the highest elevation between the two mile markers (inclusive). For the data shown above, asking for highest between 3 and 5 should result in 2900. Asking for the highest between 0 and 8 should result in 3450.

c) double getAverage (const int heights[], int size) Return the average elevation.

d) int getNumPeaks(const int heights[], int size) Return the number of peaks in the hike

e) int getNumSteepSegments(const int heights[], int size) Return the number of segments that end with a change of more than 1000 feet. For the numbers shown above, there would be 2 steep segments (from 0-1 and 4-5).

f) int getTotalChange(const int heights[], int startMile, int endMile) Return the total elevation change over the range from startMile to endMile (inclusive). Note that any change (uphill or downhill) is positive change. For example, using the sample data from earlier in the document, getTotalChange(elevations, 1, 3) should return 1100 From 1 to 2 we go from 3000 up to 3450 : a change of 450 From 2 to 3 we go from 3450 to 2800 : a change of 650

A solution without these functions will take a significant penalty even if it produces the correct output.
