I'm a beginner student learning about functions and do not understand them fully. My assignment was to write a program that deals with temperature conversion. My program had to use 6 functions (1. Program overview 2. Enter temp 3. Enter scale 4. Convert F to C 5. Convert C to F 6. Display results) It also needs to display an error message if an inappropriate input is entered for both scale (which I have) and temperature (which I do not know where to place). Appropriate values for temps are >= -459.67 F or -273.15 C. I do not know where to place this scale either. I also have multiple errors in my program. If anyone could give me any guidance in helping me to fix my program, I would greatly appreciate it!!
Code:
#include <iostream>
using namespace std;
void programOverview ();
char getScale ();
int getDegree ();
float convertFtoC (float);
float convertCtoF (float);
int getResults ();
int main ()
{
cout.precision (2);
programOverview ();
getDegree ();
getScale();
{
if (scale == "F")
{
convertFtoC();
}
else if (scale == "C")
{
convertCtoF();
}
else
cout << "ERROR: Invalid temperature scale" << endl;
}
getResults();
return 0;
}
//This function displays a brief overview explaining the program to the user
void programOverview ()
{
cout << "This program will convert a temperature reading provided in" << endl;
cout << "either Fahrenheit or Celsius to the other measurement scale." << endl;
}
//This function requires the user to enter the temperature scale to be used
char getScale ()
{
char scale;
cout << "Enter the letter of the temperature scale that will be used:" << endl;
cout << "F = Fahrenheit; C = Celsius)" << endl;
cin >> scale >> endl;
return scale;
}
//This function requires the user to enter the temperature reading in degrees
int getDegree ()
{
int degree;
cout << "Enter your temperature reading in degrees:" << endl;
cin >> degree;
return degree;
}
//This function converts a Fahrenheit temperature to Celsius
float convertFtoC (float Ftemp)
{
float Ctemp;
Ctemp = (Ftemp - 32) / 1.8;
return Ctemp;
}
//This function converts a Celsius temperature to Fahrenheit
float convertCtoF (float Ctemp)
{
float Ftemp;
Ftemp = 1.8 * Ctemp + 32;
return Ftemp;
}
//This function displays the results
{
int getResults ()
cout << "Your temperature reading converts as follows:" << endl;
cout << "Fahrenheit:" << return Ftemp << endl;
cout << "Celsius:" << return Ctemp << endl;
}
