Dynamic array in Stack?

Question

Is this correct ? This is compiled with g++ (3.4) sucessfully.

int main()
{
    int x = 12;
    char pz[x]; 
}

Answer 1

If you want a dynamic array on the stack:

void dynArray(int x)
{
    int *array = (int *)alloca(sizeof(*array)*x);

    // blah blah blah..
}
