c - Initializing a pointer to an array of integers. -

I have the following problem: I need to start a Stretch Number that represents a number, for that It requires its value, the number of separators and the dividers themselves. To store the divisor I need to use an indicator in an array of integers, and this is where the problem starts.

  type-type straight {int value; Int divisor_amount; Int (* divider) []; } Number;  

Now before I do not know how many divisors posseses my number I can not give the length of the array.

In the main function, I assign one value to each of these fields. This is not a problem for the first two variables.

  Number six; Six. Value = 6; Six.divisor_amount = 3;  

Now for the pointer I do not know how to actually start it. During class, it was said to do this:

  Six. Divisors [0] = 1; Six divisors [1] = 2; Six divisors [2] = 3;  

But then I remove this error from the compiler:

[Error] Invalid use of array with unspecified limitations

So I thought I needed to allocate some space and I tried:

  six.divisors = malloc (six.divisor_amount * sizeof (int));  

But this only gives me another error:

[Warning] Assignment from inconsistent pointer type [enabled by default]

< / Blockquote>

  int (* divisors) [];  

Incorrectly this is an indicator for the array of int .

Usage

  int * divisors;  

Your malloc allocation should work with it.
