Don't mean to be pedantic, but thats not 100% true. The C99 standard allows variable length arrays. That is, an array of automatic storage duration whose length is determined at run time.
For example the following code is valid:
int foo(int len)
{
int vla[len];
for (int i = 0; i < vla[len]; i++)
vla[i] = i;
for (int i = 0; i < vla[len]; i++)
printf("%i\n", vla[i] = i);
}
Of course VLA operands will cause problems when compiled with C++. As you mentioned you could use C or C++, you may want to consider moving to a compiler that will support C99.
of course you must also make sure that the expression you are using to specify the size of the array is defined first
