I have a working code but I need to add something that allows the code to work if for instance the temperature input was 98.6 as well as if the temperature is 98. What do I need to add?

#include <iostream>#include <string>using namespace std;int main() {   int f;   int answer;      cout << "Temp in Fahrenheit: ";   cin >> f;   cout << f << endl;      answer = (((f-32) * 5) / 9);   cout << "The temp in Celsius is " << answer << endl;   return 0;}
