A heavy ball is dropped into a lake from a height of 30.0 m above the water. It hits the water with a certain velocity and continues to sink to the bottom of the lake at this same constant velocity. It reaches the bottom of the lake 10.0 s after it was dropped. How deep is the lake?

Problem: Make a function "reverse" in your stack class that reverses the whole stack. In your driver file (main.cpp), make integer stack, push some values in it, call the reverse function to reverse the stack, and then print the stack. header and .cpp files are given below. Need to use this.

 

/*StackType.h */

#ifndef STACKTYPE_H_INCLUDED

#define STACKTYPE_H_INCLUDED

#include <iostream>

using namespace std;

const int MAX_ITEMS = 5;

class FullStack

// Exception class thrown

// by Push when stack is full.

{

  void printExceptionMsg(){

    cout<<"Stack is full"<<endl;

  }

};

class EmptyStack

// Exception class thrown

// by Pop and Top when stack is empty.

{

private:

  string reason;

public:

  EmptyStack(string reason){

    this->reason = reason;

  }

  //int x = 5;

  void printExceptionMsg(){

    cout<<"Empty stack exception thrown from "<<reason<<endl;

  }

};

template <class ItemType>

class StackType

{

public:

  StackType();

  bool IsFull();

  bool IsEmpty();

  void Push(ItemType);

  void Pop();

  ItemType Top();

private:

  int top;

  ItemType items[MAX_ITEMS];

};

The regional sales manager of pandg group interviews sales representatives in the
Midwest and asks them questions about the percentage of their time they spend making
presentations to potential new customers, talking on the telephone with current customers,
working on the computer and engaging in on-the-job activities. What potential sources of error
