Variables in variable names

Hi,
I am creating a code for a database for a uni project and I have run into a problem, and I have a subsequent question!
When creating records to go in the database (string format) I would like to name the variables data'number' , where 'number' is another variable which counts the number of records in the database. I know this is not possible because visual Studio throws up an error! So is there a way of doing something like this? I am relatively new to C and I don't know much so this would be a great help.
Thank you!

You can use sprintf() to "print" variables to a string - as that what you're after?

There's not really a way to create "dynamic" variable names in C, at least not ways that would be very useful for you.

Code:

---

$ cat cboard.c
#define VAR(x, y) (x##y)

int main(void)
{
    int VAR(Test, 12) = 5;
   
    return 0;
}
$ gcc cboard.c -E
<< snip >>

int main(void)
{
    int (Test12) = 5;

    return 0;
}

How would this differ from an array like data[number]?

You can create dynamic arrays just fine in C.

Code:

---

int number = 10; // you get this from wherever you want
int *data = malloc( number * sizeof(*data) );
