New guy here. I'm barely in my second C++ class, and we are doing some review and I cannot figure out why this won't give me what I want. The problem is to create a function to convert Fahrenheit to Celsius. It's to be enclosed in a loop so that my output is a list that shows what 1-20 degrees fahrenheit is in Celcius. This is my code:


// Celcius Temperature Table

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

double celsius(double);

int main()
{
double fah, cel;
cout << fixed << showpoint << setprecision(1);

cout << "Fahrenheit\tCelcius\n";
cout << "----------------------\n";
for (fah = 0; fah <= 20; fah++)
{
cel = celsius(fah);
cout << fah << "\t" << cel << endl;
}
return 0;
}

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



I can't see what is wrong, but whenever I compile it, it loops like it should and lists Fahrenheit 1-20, but in the celcius column every value is 0.0. Can someone help me out, or at least give me a hint about what I'm doing wrong?

Hint: In C(++), 5/9 is not the same as 5.0/9.0.

Oh man. That was it. I've been going crazy trying to find out what was wrong. I definitely won't forget this again. Thank you.
