Hello!
I'm studying C for some exams I have
In my book I'm writing exactly the code it provides and I believe it's wrong somehow

Code:
#include <stdio.h>
void main(int argc, char **argv)
{
    double f , c;
    printf("Give Temperature in Fahreneit:");
    scanf("%g" , &f);
    c = 5.0 * (f-32) / 9.0;
    printf("Celcious Degrees: %g" , c);
    return 0;
}
I'm using Codeblocks, the suggested C compiler from the website
