Taking structs to the next level

Hey me again.

Ok for my gym program, i've got a struct like this

Code:

---

typedef struct weights{
            int reps;
            int sets;
            int weight;
            }exercises;

---

this is good because i can call it as follows exercises benchpress.reps = 5;

Now suppose i want to take this one step further and have a struct which holds the information for a weights routine as opposed to just a single exercise. How do i go about this. Each routine would have a different number of exercises. Im not sure how to add this other level to stucts.

I'd like to have a struct of routines, that i could call with

routines.chestAndTriceps

in this sub heading if you like would be a list of mabye 7 exercises all of wich ideally are individual members of the exercises struct.

I dont even really know if its possible and im not 100% sure of what im asking for or how to put across what im looking.

But if my some miracle you understand, id appreciate a push in the right direction

I suspect what you really want is a struct like this:

Code:

---

typedef struct weights{
            int reps;
            int sets;
            int weight;
            char *name;
            }exercises;

// Then:
excercises routines[] =
{
    { 0, 0, 0, "Benchpress" },
    { 0, 0, 0, "ChestAndTriceps" },
...
};

My Hat of Guessing gives you the following code to look at:

Code:

---

typedef struct {
    int reps;
    int sets;
    int weight;
} exercises;

typedef struct {
    int numOfExercises;
    exercises *exerciseList; /* to be interpreted later as an array */
} routines;

.
.
.
routines chestAndTriceps;
chestAndTriceps.numOfExercises = 7;
chestAndTriceps.exerciseList = malloc(sizeof(exercises)*7); /* allocate memory for "array" */

---

The "variable-size array" might be a bit more complex than you want, but that should give you a shove (whether in the right direction or in the mud is yet to be determined).

Edit to add: and you would then access elements of your exercises as

Code:

---

chestAndTriceps.exerciseList[0].reps /*et cetera*/

---

Thanks guys. Tabstop, i think thats exactly what i need.

Thanks alot.
