Question

Below is the code that will not increment correctly. "END" number will not show the program stops at the number before it.

#include <iostream>

#include <string>

#include <stdlib.h>

#include<iomanip>

using namespace std;

double FtoC(double);

void displayMenu()

// display the main menu

{

cout << "Welcome to the temperatures convertor program" << endl;

cout << "Please select one of the following options: " << endl;

cout << "(F/f) From Fahrenheit to Celsius" << endl;

cout << "(C/c) From Celsius to Fahrenheit" << endl;

cout << "(Q/q) Exit" << endl;

char getMenuSelection()

// menu selection from the user

{

cout << "-- Invalid selection: try again --" << endl;

cout << endl;

displayMenu();

cout << "Please select an option: ";

cin >> selection;

cin.clear();

}

return selection;

}

void getStartEndAndIncrement(int& start, int& end, int& increment)

// Asks for the start, end and increment values

{

cout << "Enter 3 integers: starting temperature, ending temperature, and an increment" << endl;

string tmpStart = "", tmpEnd = "", tmpIncre = "";

cout << "starting temperature: ";

cin >> tmpStart; cin.clear();

start = atoi(tmpStart.c_str());

end = atoi(tmpEnd.c_str());

increment = atoi(tmpIncre.c_str());

}

double CtoF(double celsius)

// converts a celsius temperature to Fahrenheit

{

return (9.0/5.0)*celsius + 32; } double FtoC(double fahrenheit)

// Converts a Fahrenheit temperature to celsius

{

return (5.0/9.0)*(fahrenheit-32);

}

void displayTable(char option, int startTemp, int endTemp, int increment)

// Displays table

{
