Question

For ease of printing, I want to create one array of pointers to the elements of my struct. How can I do that? My attempt is on the last line of the struct. Just as a note, this struct has other values than int, that are now showed here. I want this sort of indexing only for the ints.

struct status {
    int lastinputVac;
    int inputVac;

    int outputVac;

    /* The unit is % */
    int outputpower;

    int outputHz;

    /* The unit is % */
    int batterylevel;

    int temperatureC;

    int *ordered_values[] = { &lastinputVac, &inputVac, &outputVac, &outputpower, &outputHz, &batterylevel, &temperatureC };
}

Just bite the bullet and write the extra code to print it with struct member access. It’s not worth compromising your design to save a few lines of code.

Imagine you have to expose this struct in a library some day. Do you really want to load the user down with this weird pointer array that serves no real purpose?
