C program to convert Fahrenheit to Celsius always prints zero

Question

I need some help with a program for converting Fahrenheit to Celsius in C. My code looks like this

#include 
int main(void)
{
    int fahrenhe         


        

Answer 1

try celsius = ((double)5/9) * (fahrenheit-32); Or you can use 5.0.

The fact is that "/" looks at the operand type. In case of int the result is also an int, so you have 0. When 5 is treated as double, then the division will be executed correctly.
