Question

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

#include <stdio.h>
int main(void)
{
    int fahrenheit;
    double celsius;

    printf("Enter the temperature in degrees fahrenheit:\n\n\n\n");
    scanf("%d", &fahrenheit);
    celsius = (5 / 9) * (fahrenheit - 32);
    printf("The converted temperature is %lf\n", celsius);

    return 0;
}

Every time I execute it it the result is 0.000000. I know I’m missing something but can’t figure out what.

Answer 1

5/9 will result in integer division, which will = 0

Try 5.0/9.0 instead.
