This code is supposed to calculate and print out the temperature where the temperature in celsius is the same in Fahrenheit. So it should print -40 but instead it prints nothing. Please help.
Code:#include<iostream> using namespace std; int main() {int celsius=100, fahrenheit; do { fahrenheit=9/5*celsius+32; celsius--;} while(celsius+1!=fahrenheit); cout<<"Celsius and fahrenheit are the same at "<<fahrenheit; return 0; }
9/5 is 1 in C++
You should reorganise that expression so that the multiplication is executed before the division
That's horrible formatting btw, never put the closing brace on the end of a line of code.
Add some whitespace too.

Indent, format. 9/5 is integer divsision; thus it yields one. If you do 9.0/5, you should see that you'll get some different answers.

abs( fahrenheit - celsius ) < 0.0001
Or however close you want to be, but not exact.
