Value not getting right answer

Question

int c;
int f = 20;
c = 5 / 9 * (f - 32);
Console.WriteLine(c);
Console.ReadLine();

If I run this code c ends up being 0, which is wrong. Can anyone tell me why?

Answer 1

Because your calculation is being done in integer type. I believe c is double type variable.

c = 5d / 9 * (f - 32.0);

use 32.0 or 32d so that one of the operands is double, also do the same for 5/9.

Also you need to define c as double.
