Function help

My output for the variable celsius is 0 everytime. I can't figure it out =(. Can anyone spot what is wrong?

Code:

---

#include <iostream>
using namespace std;

double get_celsius(double);

int main()
{
        double fahrenheit, celsius;

        cout << "This progam converts fahrenheit to celsius.\nPlease input a fahrenheit temperature...\n";
                cin >> fahrenheit;

        celsius = get_celsius(fahrenheit);

        cout << fahrenheit << " fahrenheit is " << celsius << " celsius.\n";
        return 0;
}

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

---

Hint: with integer division, 5/9=0

Ok, i just put .5555 instead of 5/9, how would you code 5/9 to work?

Code:

---

double get_celsius(double fahrenheit)
{
  double x = 5/9,
              result;
 
    result = (fahrenheit - 32) * x;
    return result;

---

would that work?

An easy way is to write 5.0/9.0 instead.

Hint:
5 == treated as an integer
5.0 == treated as a double
5.0f == treated as a float
