Question

Modify this code to display the message "That's hot!" if the temperature entered is greater than 90 degrees Farenheit or equivalent Celsius, or the message "That's cold!" if the temperature entered is less than -10 degrees Farenheit or equivalent Celsius. And to show one in between where it doesn't show any message.


#include <iostream>
#include <iomanip>
using namespace std;

// a temperature conversion program
int main()
{
  char tempType;
  double temp, fahren, celsius;

  cout << "Enter the temperature to be converted: ";
  cin  >> temp;
  cout << "Enter an f if the temperature is in Fahrenheit";
  cout << "\n or a c if the temperature is in Celsius: ";
  cin  >> tempType;

    // set output formats
  cout << setiosflags(ios::fixed)
       << setiosflags(ios::showpoint)
       << setprecision(2);

  if (tempType == 'f')
  {
    celsius = (5.0 / 9.0) * (temp - 32.0);
    cout << "\nThe equivalent Celsius temperature is "
         << celsius << endl;
  }
  else
  {
    fahren =  (9.0 / 5.0) * temp + 32.0;
    cout << "\nThe equivalent Fahrenheit temperature is "
         << fahren << endl;
  }

  return 0;
}

Answer 1

I have modified the code as requeired.

I have added comments // hot temperature and // cold temperature before printing the message

Please find updated code

Farenheit or equivalent Celsius, or the message
"That's cold!" if the temperature entered is less than -10 degrees
