Write a method called dangerousDescent that determines whether there is a downhill section in the hiking trail with a gradient of more than -5%. The gradient is calculated by the rise in elevation over the run in distance. For example, the last kilometer section has a gradient of -1% because the rise in elevation is 40 - 50 = -10 meters. The distance covered in 1000 meters. -10 / 1000 = -1%.

Your method should return true if there exists a dangerous descent in the given array, false otherwise.

the explanation gives you the code used

Explanation:

There are several ways to go about this, here is just one way to carry out this computation.

#include <iostream>

using namespace std;

bool dangerousDescent(int* elevationArray , int sizeOfElevationArray)

{

  //we calculate gradient throughout elevationArray and if any one of them is more than -5%

  //then return true else return false

  //gradientOfSectionX = rise in elevation/Distance covered in merters

  //where rise in elevation is (elevationOfX - elevationOfX_previous)

  bool isDangerousDecent = false;

  float gradient = 0;

  int threshold = -5;

  float riseInElevation = 0;

  for (int i = 0; i < sizeOfElevationArray && isDangerousDecent == false; i++)

  {

      if (i > 0)

      {

          //check to avoid array out of bound error

          riseInElevation = (elevationArray[i] - elevationArray[i - 1]);

          gradient = riseInElevation / 1000; //1000 meters = 1km because every marker is at 1 kilometer distance

          gradient = gradient * 100; //percentage

          if (gradient > threshold)

          {

              isDangerousDecent = true;

              cout << "There is a gradient of " << gradient << "% on section " << elevationArray[i] << " of hiking trail " << endl;

          }

      }

      //first section not included because that was starting point with 0% elevatoin

  }

  return isDangerousDecent;

}

int main()

{

  int elevationArray[] = { 100,50,20,30,50,40 };

  int size = sizeof elevationArray / sizeof elevationArray[0];

  if (dangerousDescent(elevationArray, size) == true)

  {

      cout << "There is a dangerous decent of gradient more than -5% in hiking trail " << endl;

  }

  else

  {

      cout << "There is no dangerous decent of gradient more than -5% in hiking trail " << endl;

  }

  system("pause");

}

answer is:

a). backstage view

explanation:

backstage view is the area where files and data about them is managed— creating, saving, printing, sending to others, inspecting for hidden metadata or personal information, and setting options. so in this way we can add many things to our document swiftly.

i hope you get the idea.
