Question

Write a C++ program that prompts a user to enter a temperature in Fahrenheit as a real number. After the temperature is entered display the temperature in Celsius. Your program will then prompt the user if they want to continue. If the character n or N is entered the program will stop; otherwise, the program will continue. After your program stops accepting temperatures display the average of all the temperatures entered in both Fahrenheit and Celsius. Be sure to use a C++ function to compute the conversion from Fahrenheit to Celsius.

Enter a temperature as Fahrenheit: 98.6

98.6F is 37.0C

Do you want to continue (Y/N)?

Y

Enter a temperature as Fahrenheit: 212.0

212.0F is 100.0C

Do you want to continue (Y/N)

N

The averages are 155.3F, and 68.5C

Answer 1

Below is your code: -

#include<iostream>
using namespace std;

int main() {
   double sumOfF = 0;
   double sumOfC = 0;
   int count = 0;
  
   while(true) {
       double tempInF;
       cout<<"Enter a temperature as Fahrenheit: ";
       cin>>tempInF;
       sumOfF = sumOfF + tempInF;
       double cel = (tempInF - 32) * 5.0/9.0;
       sumOfC = sumOfC + cel;
       count++;
       cout<<tempInF<<"F is "<<cel<<"C"<<endl;
       char choice;
       cout<<"Do you want to continue (Y/N)?"<<endl;
       cin>>choice;
      
       if(choice == 'n' || choice == 'N') {
           break;
       }
   }
  
   cout<<"The averages are "<<(sumOfF/(double)count)<<"F, and "<<(sumOfC/(double)count)<<"C"<<endl;
}

Output

Enter a temperature as Fahrenheit: 98.6
98.6F is 37C
Do you want to continue (Y/N)?
Y
Enter a temperature as Fahrenheit: 212.0
212F is 100C
Do you want to continue (Y/N)?
N
The averages are 155.3F, and 68.5C
