1. congratulations your first lesson in debugging - look through you code and find where you would get the value -32. forget about what values variables are suposed to be.

also, the inner set of {} is unnecessary

edit: scribbler beat me to this

2. I believe your problem is right on this line: float b = ( 5/9 * a - 32 ) ;

More precisly 5/9, that is integer division and it is my bet that this is evaluated to 0, so basicly your expression looks like this:
float b = ( 0 * a - 32 ) ;

To fix you have to make sure you tell the compiler that you dont want integer division, by doing this: float b = ( 5.0f/9.0f * a - 32 ) ;

The trailing f is just to tell the compiler its a float and not a double.

Edit: awwwwww beaten!

3. I got it, finaly, thanks

4. actually, it was that i didnt have "()" around "a - 32", it did the multiplication first, thats why I got that answer
Code:
```#include <iostream>

using namespace std;

int main()
{
int a;

cout<<"Enter Farenheit temperature to convert to Celcius:\n";
cin>> a;
float b = (5.0/9.0 * (a - 32) ) ;
cin.ignore();
{
