Please I need help to write this program by using C++.

The formula for converting a temperature from Fahrenheit to Celsius is C =5/9(F - 32) where F is the Fahrenheit temperature. Write a function named celsius that accept a Fahrenheit temperature as an argument. The function should return the temperature, converted to Celsius. Demonstrate the function by calling it in a loop that display a table of the Fahrenheit temperature 0 through 20 and their Celsius equivalents.

Solution

Temp.cpp

#include <iostream>
#include <iomanip>
using namespace std;
double celsius (double fahrenheit);
int main()
{
for(double i=0; i<=20; i++){
       double c = celsius (i);
       cout<<fixed<<setprecision(2)<<\"Fahrenheit Temparature: \"<<i<<\" Celsius Temparature: \"<<c<<endl;
       }

return 0;
}

   double celsius (double fahrenheit){
       double celsius = ( 5 /(double) 9 ) * ( fahrenheit - 32 );
       return celsius;
    }

Output:

Fahrenheit Temparature: 0.0 Celsius Temparature: -17.78
