Array size set by variable

Hi,

I am having issues compiling a program with cc on a fairly old unix system, I understand that I need to follow C standards strictly but I can find no way around this.

Code:

---

array(int n)
{
int i;
int array[n];

for(i=0;i<=n-1;i++)
        {
        array[i]=i+1;
        }
        exit(0);
}

---

It is a simple function to setup an array to size n which is collected and passed in from the main function. The compiler is freaking at the array declaration, saying that I have declared an array of 0 and that the expression is not constant, as it compiles line by line and this is the last function I am happy with the rest of my code.
Does anyone have any ideas how I can get around this?

Thanks

Turn on the C99 switch in your compiler. Else, get a new compiler. Else, malloc memory from the heap for your array instead of statically allocating it in the stack.

Variable length arrays are standard, but were introduced in the 1999 version of the C standard. Your system probably has a compiler that does not support that. As such, use pointers with malloc/realloc/calloc/free instead.

Thanks for the quick replies, have managed a solution using malloc.

Thanks again.
