Question

I am trying to write a program that produces a table thatshows the conversions from Fahrenheit to Celsius for values from 0degrees F to 100 degrees F, and I need a line for every 5 degreeincrement. I have the Fahrenheit side set up fine, but all myvalues of Celsius come out as -32. I have thefollowing:
#include <iostream> #include <iomanip> #include <cmath> using namespace std; int main () {    double TF=0, TC;    cout<<"****Fahrenheit toCelsius*****"<<endl;    cout<<" "<<endl;    cout<<"Fahrenheit    "<<"Celsius"<<endl;    while(TF<=99)    {    TF+=5;    TC=(5/9)*TF-32;    cout<<"   "<<TF<<setw(20)<<TC<<endl;    }    system("pause");    return 0; }

any ideas?

Explanation / Answer

In your line "TC=(5/9)*TF-32;" Try instead "(5.0/9.0)*TF-32.0;" You need to use float values, not integer values (otherwise thecompiler just assumes an int, and rounds down). As a side note, if you had a variable which contains an integer,you can go float(variablename) and have it treated as a float (soyour result isn't rounded down).
