Allow the user to enter a Fahrenheit temperature to convert or to end the program.

2) The program must have three programmer-defined functions:

Option 1: Conversion from Fahrenheit to Celsius

Option 2: Conversion from Fahrenheit to Kelvin

Option 3: Conversion from Fahrenheit to Rankine

Option 4: exit

Here is my C++ programming so far

using namespace std;

double FahrToCelsius(double Celsius);

double FahrToKelvin(double Kelvin);

double FahrToRankine(double Rankine);

int main()

{

// Declare Variables

double C, F, R, K;

cout

cout

cin >> F;

cout

cout

cout

return 0;

}

double FahrToCelsius(double F)

{

double C=(F-32)*(5/9.0);

return C;

}

double FahrToKelvin(double F)

{

double K=(F+459.67)*(5/9.0);

return K;

}

double FahrToRankine(double F)

{

double R=(F+459.67);

return R;

}

C++ programming 1) Allow the user to enter a Fahrenheit temperature to convert or to end the program. 2) The program must have three programmer- defined functions a) Conversion from Fahrenheit to Celsius b) Conversion from Fahrenheit to Kelvin c) Conversion from Fahrenheit to Rankine Output: Please choosing one of the following 1. Conversion from Fahrenheit to Celsius 2. Conversion from Fahrenheit to Kelvin 3. Conversion from Fahrenheit to Rankine 4. End the program Enter number: 1 Enter Fahrenheit temperature: 0 32 Celsius Please choosing one of the following 1. Conversion from Fahrenheit to Celsius 2. Conversion from Fahrenheit to Kelvin 3. Conversion from Fahrenheit to Rankine 4. End the program Enter number: 4 End the program
