need to use double instead of int, and change all of the values to whatever.0
Also last part should be ((5.0/9.0)*(x-32.0));
And actually it doesn't really work at all the way you have it set up. Try this:
using namespace std;
double x , c;
c = (5.0 / 9.0) * (x - 32.0);
cout<<"The temperature in fahrenheit is: "<<x<<"\tThe temperature in celsius is: "<<c<<endl;
This is working for me.
