Resistor color in C

Exercism Bugs & Feature Requests
1

The tests of this exercise fail due to implicit declaration in them. Can someone help?

2

Share your resistor_color.h and resistor_color.c code please.

Here’s the header file

#ifndef RESISTOR_COLOR_H
#define RESISTOR_COLOR_H

typedef enum {
    BLACK,
    BROWN,
    RED,
    ORANGE,
    YELLOW,
    GREEN,
    BLUE,
    VIOLET,
    GREY,
    WHITE
} resistor_band_t;

#endif

And the .c

#include "resistor_color.h"

int                color_code(resistor_band_t color);
resistor_band_t    *colors();

int    color_code(resistor_band_t color){
    return color;
}

resistor_band_t    *colors(){
    static resistor_band_t color_list[10];

    for (resistor_band_t keyword = BLACK; keyword <= WHITE; keyword++){
        color_list[keyword] = keyword;
    }
    return color_list;
}

Thanks!

Could you share what fails?

Note your header doesn’t declare any functions. The header needs to declare the functions for the tests to use them.

That was the problem! :sweat_smile: I passed other exercises without declaring functions in the header file, they were already there… Thank you!
